Can a light be on two circuits?
You may not have two (different) circuits powering the same light bulb. You can make the two switch locations into a 3 way switch setup, power from one circuit to one switch, 3 wire cable between the switches, 2 wire cable to the light.
How do you connect a bulb to a relay?
The connections for the relay is simple. We take a wire from the light bulb and cut it so that we have two separate wires just like it is shown in the picture above. Then we put one wire into the NO (normally open) pin of the relay, and the other wire into the COM (common) pin of the relay.
Can relay be used for switching?
Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps.
Can one switch control 2 circuits?
Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. A double pole switch can be used to control light and a fan or 2 lights on separate circuits.
How do you separate two lights on the same switch?
2 Answers
- Get a 2-gang box to replace your existing 1-gang box.
- Get a new switch.
- Remove your existing box and install the 2-gang box in its place.
- Run your supply hot wire to both switches.
- Connect the light/fan hot wire to one switch and the exterior light to the other.
- Join all neutrals and ground wires.
How do you wire a regular open relay?
If you want a normally closed relay, you will want to wire to 87a. If you want a normally open relay, you will wire to 87. Although most relays are labeled at the bottom, you can always find the 30 pin set perpendicular to pins 87 and 87a for easy identification to the power source.
How to wire two light switches with one power supply?
How to Wire Two Light Switches With 2 lights with One Power Supply diagram I want to wire 1 way switch, 1 dimmer switch with 2 individual lights from one powe source. Thank, frank Suzanne B. DIY

How does a 2 way light switch work?
2 way light switch with power feed via switch (two lights) This circuit is a simple 2 way switch circuit with the power source via the switch to control multiple lights.
How do you hook up a light switch?
Connect the wires to the receptacle issuing the power to the switches. You will want to once again strip about an inch or so of the wires, and then attach them to the green ground, and then securely attach it with a screw. Then, you will need to attach the white wire to the silver terminal, as well as the black wire to the brass terminal.
