I believe that it is a grounding switch. If that is the case it would only have one wire going to the switch. You could run this wire to any fused constant hot. The wire would run from the hot, to the light, to the switch.
To wire multiple lights to one switch, you can connect the lights in parallel by running a cable from the switch to each light fixture. Make sure to connect the hot wire from the switch to the hot wire of each light, and the neutral wire from the switch to the neutral wire of each light. This will allow you to control all the lights with a single switch.
Yes, you can extend power through the 3-wire switch leg to a new switch for a new light. You would need to connect the hot wire to the common terminal on the existing switch, then extend the hot wire to the new switch, along with the traveler wire. At the new switch, connect the hot wire to the common terminal and the traveler wire to one of the traveler terminals.
The one wire carries the electricity or voltage. The lamp is grounded completing the circuit. You don't. The light switch is only half the circuit, a lamp has nothing to ground to so it can not work. If the wire to the switch is 3 wire, the bare wire would complete the circuit and power the plug, but it would not be up to code and could present a fire hazzard.
To wire two lights to one switch, you will need to connect the power source to the switch, then run a wire from the switch to the first light, and another wire from the first light to the second light. Make sure to follow proper safety precautions and consult a professional if needed.
A switch is inserted in series with a single wire. When the switch is on, it is as if the wire had not been opened to insert the switch. When the switch is off the wire is open and no current can flow. All a double pole switch does is allows you to switch two separate wires at the same time with the same switch action. A single pole switch just switches one wire.
To wire an up-down switch, you would typically connect the power source to one terminal of the switch and the load (such as a motor) to the other terminal. When the switch is in the up position, it sends power to the load to move it in one direction. When the switch is in the down position, it reverses the polarity of the power to the load to move it in the opposite direction. Make sure to follow the wiring diagram provided with the switch to ensure proper installation.
No. For any 3 way switch installation you need 2 "travelers" between switches and these conductors cannot be used for any other purpose. The 3rd wire is used for a neutral or switch leg, depending on the needs of the circuit, but is not connected to both switches. The neutral is not connected to either switch.
If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
Yes. You have 2 wires (plus ground) coming from the previous switch in the circuit and 2 wires (plus ground) going to the next switch in the circuit. If you have a neutral, or if you have a switch leg, which would be the conductor from the last switch in the circuit to the equipment being powered, you will need 3 or 4 conductors (plus ground).
To properly wire a 2 pole switch in a circuit, connect the hot wire to one terminal of the switch and the load wire to the other terminal. Make sure to connect the ground wire to the switch's grounding terminal for safety. This setup allows the switch to control two separate circuits simultaneously.
Connect the black wire to the single switch hole, the brown wire to one of the holes on the double switch, and the gray wire to the other hole on the double switch. The earth wire should be connected to the grounding point on the light switch. Make sure to follow proper safety procedures and consult a professional if you are unsure.
