How to wire a single switch.
Electronic wireless light switch circuit diagram.
This diagram illustrates wiring for one switch to control 2 or more lights.
Pin1 of both the switches are connected with the phase or live wire and pin2 of both the switches are connected with the one end of the lamp.
The circuit is built around an ic ca3140 irled1 photo transistor and other discrete components.
Switch wiring shows the power source power in starts at the switch box.
The source is at sw1 and 2 wire cable runs from there to the fixtures.
As you can see in the schematic diagram of 2 way switch circuit below the common of both the switches are short circuited.
The other end of the lamp is connected with neutral line of ac power supply.

When regulated 5v is connected.
This circuit is very stable and sensitive compared to other ac appliance control circuits.
Circuit electrical wiring enters the switch box.
Rotating led chakra circuit for god idols.
The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light.
Touch dimmable led light bar circuit.
In this project we designed a simple wireless switch that uses simple hardware to achieve the action of switching.
You just need to move your hand between the infrared led ir led1 and the phototransistor t1.
The wireless light switch circuit described here requires no physical contact for operating the appliance.
It is simple compact and cheap.
Current consumption is low in milliamperes.
The circuit diagram circuit description and working are described in the following sections.
Wireless music level indicator circuit.
The most common type of wireless communication between the switch and the appliance is rf transmission.
Featuring wiring diagrams for single pole wall switches commonly used in the home.
Explanation of wiring diagram 1.
We toggle the switches to turn the appliance on or off.
Wireless on off switch active high pass filter using lm741 inverters and converters.
So today we are building a simple wireless switch circuit in which there is no need of physical contact with the switch just one has to take his hand over the switch and it turns on off the light.
You may use this wireless light switch instead of physical contact with switches which may be dangerous if there is any shorting.
