Example 1: Basic Light Switch Wiring Diagrams

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 15 minutes creating this sample.

This sample shows a set of basic wiring diagrams of the light switches. You can see the schematics of the correct use of junction boxes and switches. The junction boxes help to avoid problems with many wires. Because sometimes the superfluous wires are connected in a small outlet box that makes a mess and inconvenience. As for the switches, the use of two or more electrical switches is widespread. Numerous switches allow controlling an electrical load and lighting from more than one location. The installation of the two-way, three-way or four-way switches allows you to control a light from the corresponding number of locations. These can be opposite sides of a large room, a long hallway, the top and bottom of a stairway, etc. These schematics are basic and you can easily modify them according to your needs and requirements. At the use of parts with metal cover, add a ground wire or use the knots with dielectric cover.

Example 2: CCFL Power Supply Wiring Diagram

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 10 minutes creating this sample.

This Wiring diagram shows the power supply circuit with CCFL. The cold-cathode fluorescent lamps (CCFLs) are the components of the gas-discharge lamps, neon lamps, cold-cathode lamps, vacuum and discharge tubes, cold-cathode switching tubes, thyratrons, krytrons, cold-cathode displays or Nixie tubes, etc. A cold cathode isn't heated previously and isn't heated electrically by a filament. But it doesn't mean that cold cathode operates at a low temperature. Typically, similar to the hot cathode, it is heated to the operating temperature during work. The current passing from the cathode into the gas is used to heat it. The cold-cathode fluorescent lamps emit more electrons than the thermionic emission offers. However, they use higher voltages than hot-cathode lamps. The cold-cathode lamps using the CCFLs contain a discharge in mercury vapor that develops ultraviolet light and causes the emission of visible light. These lamps are used for backlighting the LCDs.

Example 3: Doorbell Wiring Diagram

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 10 minutes creating this sample.

This Wiring diagram shows a typical doorbell circuit. Being a type of signaling device, a doorbell is installed outside the apartment, house, or another premise. Typically, it is placed next to the entrance door. Being activated, in common by a simple press, it provides the bell ring inside the corresponding premise. A doorbell includes three main parts: the push button, the chime, and the transformer. These parts are connected with wires in a doorbell of a wired-type system. This diagram is a simple guide on how to wire a doorbell. Hot and neutral wires are differentiated by colors: red and blue. The mechanism of work is quite simple. When the doorbell button is pressed, the doorbell circuit is closed and the doorbell rings. But the doorbell cannot be connected directly to the electrical system and requires a lower voltage. The transformer is used to reduce the voltage from 120 or 240 volts to the value at which the doorbell operates (10-24 volts). Usually the doorbell transformer is connected to an electrical junction box.

Example 4: Lightdimmer Phase Control Circuit

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 10 minutes creating this sample.

This sample shows a simplified schematic of a phase control circuit used for dimming a light. The dimming process is generally directed at the control of the amount of electrical power supplied to a light source and changing brightness. The different types of dimming are applied. The universal dimmers are most widespread, they recognize the load characteristics and adjust the control method accordingly. More complex circuits are controlled by the phase control dimmers. At the same time, because the discharge is destroyed at low voltage, fluorescent lamps and gas-discharge lamps cannot be darkened. The use of potentiometer P in this diagram allows changing the brightness of the incandescent lamp La. The lamp is controlled by a triac Tr and is lit via diac Di. R1 and C1 reduce the hysteresis, and R2 and C2 form two phase shifts. AC voltage has a delay. The lower the resistance of the potentiometer P is, the earlier Di and Tr will light up and the lamp will light brighter. A collection of electrical symbols included to the libraries of Home Automation and Wiring solution is a perfect assistant in designing home automation diagrams and plans.

Example 5: Low Voltage Doorbell Wiring Diagram

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 10 minutes creating this sample.

This sample shows a wiring diagram for the low voltage doorbell. The circuit includes a fuse box and junction box. The fuses are devices installed in electrical systems to protect them against potential dangers. Among the primary dangers are power surges or excessive temperatures. And a fuse box is a metal container for the fuses. Several fuses for the electrical system of a single house or apartment are placed in a fuse box. Typically, fuse boxes are sized for 6-12 fuses. An electrical junction box or jbox is a housing that contains electrical connections. It prevents accidental electric shock and protects electrical connections from the weather elements. It is surface mounted or recessed into a wall, ceiling, floor, etc. The low voltage doorbell circuit necessarily includes a transformer to step down the voltage from a high AC power to a lower one. This circuit uses two wires, hot and neutral, colored differently: red and blue.

Example 6: Thyristor Light Power Regulator

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 15 minutes creating this sample.

This diagram sample shows the electrical schematic of a light power regulator using a thyristor. The thyristor light power regulator allows you to change the power supplied to the load due to the delay in turning on the thyristor in the half-cycle of the alternating current. The thyristor is a key component of this circuit. When a signal appears on the control electrode, the thyristor opens. The longer the switch-on delay is, the less power is supplied to the load. Transistors VT1 and VT2 operate in the key mode. When the voltage on the capacitor C1 is equal to the voltage at the point between the resistors R3 and R4, the transistors open. They send a signal to the control electrode of the thyristor VS1. The capacitor is discharged and the thyristor opens until the next half cycle. This circuit is quite simple and starts working immediately after switching on. It is mainly applied to power control of AC loads, universal collector motors, incandescent lamps. However, the use of 5 power elements that heat up during operation is its key disadvantage compared to triac regulators using one power element.

Example 7: TRIAC Light Power Regulator

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 10 minutes creating this sample.

This sample shows a circuit of a triac light power regulator. Triacs are used in AC circuits to conduct current. They act as regulator keys used to create circuits. Triacs are semiconductor elements related to thyristors. Typically, a triac includes three outputs: one control (gateway G) and two power outputs (anodes A1 and A2), which, when triggered, conduct current in two directions. The triac is turned on by the gate current and, accordingly, turned off in the absence of current. Triacs are often used as bi-directional connectors, relays, or power regulators. They work in both directions of polarization and behave like thyristors in the positive part. Triac switching occurs regardless of polarization. Triacs are widely used in electronics. They are used in motor speed controllers, electric fans, home appliances, dimmers and more. Use the drawing tools in ConceptDraw DIAGRAM and Home Automation and Wiring to efficiently create circuits with all the elements you need, including triacs, diacs and more.

Example 8: Wiring Diagram Fusebox 2-Switches 2-Lamps Socket

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 5 minutes creating this sample.

This electric diagram includes a fusebox, two switches, two lamps, and a socket. The lamps in this schematic are switched on independently of each other. The lights located in different rooms have their own different connection schemes and differ in the number of switches. Switches and sockets are used to control the lights. Typically, the lighting fixtures on walls and ceiling do not have plugs and are switched using switches mounted on the wall. In addition, the lights of different and the same types of connection are also often combined in one room. In any case, they are connected as parallel consumers. The switch is connected to the lamp by a special conductor called a switched conductor. Some devices include an internal circuit allowing them to work for a certain time even after switching off. The bright colors are applied in Wiring diagrams for a visual effect and to highlight important points. Use the pre-made wiring diagram symbols from the libraries of Home Automation and Wiring solution to construct efficiently your own Wiring diagrams.

Example 9: Wiring Diagram Fusebox 2-Switches Lamp

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 5 minutes creating this sample.

This electrical wiring diagram shows the connection of a lamp. A fuse box is used to protect the buildings and premises from overloads and their consequences. The electricity is supplied to consumers from the fuse box. Each individual circuit in the fuse box is powered by three contacts: neutral conductor (N), phase (L), and protection conductor (PE). At the same time, the protection conductor is never interrupted and is a part of the protective mechanism. A voltage exists between the neutral conductor and the phase. This schematic includes one lamp, a fusebox, and two switches. The switches are interconnected by two conductors and are used to switch on the lamp. The conductor between the switch and the lamp is a switched conductor. One of the conductors is connected to the phase. If it is also connected to the lamp via another switch, the lamp lights up.

Example 10: Wiring Diagram Fusebox 3-Switches Lamp

This diagram was created in ConceptDraw DIAGRAM using a combination of libraries from the Home Automation and Wiring Solution. An experienced user spent 5 minutes creating this sample.

This diagram shows a circuit that includes a lamp and three switches. The switches are cross-linked. The circuit includes two single switches and one double. Two switches are reconnected to two corresponding switches. A two-position switch connects two other switches in parallel. Two switches conduct phase current. The lamp lights up when the first switch is connected to the second in phase, and the third switch to the fourth in antiphase. The switches are toggled from bottom to top and up to down. This is why they overlap. ConceptDraw DIAGRAM software and home automation and wiring solution enable you to create a wide variety of wiring diagrams, electrical wiring diagrams, home appliance wiring plans and more. Use it to create circuits with one, two or more switches, one or more lamps, and a fuse box, sockets or without them and more diagrams.
