Yes, it is legal to have two circuits in one switch box as long as proper electrical codes and regulations are followed, and the box is sized appropriately to accommodate the wiring for both circuits. It is important to ensure that each circuit is clearly labeled and properly insulated to prevent any safety hazards.
a separate contact: single pole switches have one contact, double pole two, etc.throws in a switch are the number of ways the switch may be set.SPST - one contact that can only be turned on/off.SPDT - one contact that can be switched two ways.6P4T - six contacts that can be switched four ways, usually a rotary switch.etc.
Follow the instructions. I assume you are trying to switch 2 circuits with one switch. I always do a continuity test with an electrical meter to find which terminals to use. Usually one circuit will be wired on the left and one on the right.
Double pole refers to a switch that controls two separate electrical circuits, while triple pole refers to a switch that controls three separate electrical circuits. Triple pole switches are typically used for applications that require more complex wiring configurations or higher voltage control compared to double pole switches.
Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.
You could replace the vent fan with a new one that has an on/off switch operated by a pull-cord. You will still need to have the light switched on to be able to run the fan but you would be able to switch off the fan whenever you don't need it running. To be able to switch them separately you would need to add a separate hot wire and switch. There is probably not one already in place. If the fan has a wire running directly to the switch box, and the light has a wire running directly to the same switch box, then it may be easy to install two switches instead of one. If the wire runs from the switch box to the light and then loops to the fan, then new additional wiring would be needed to obtain a separate switch control for the fan. In certain localities, like New York City the housing code requires the fan to come on with the light in apartment buildings. SAFETY ADVICEBefore you do any work yourself,on household electricity supplies, equipment or appliances,always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. === ===
An optical switch is a switch that enables signals in circuits to be switched from one circuit to another.
A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
legal to own one but illegal to carry
A single pole light switch controls one circuit and has one switch, while a double pole light switch controls two circuits and has two switches.
Switch breaks collision domains, creates virtual circuits for each connection also it does not share bandwidth of one port with others.
You can find information on a VGA switch box online at the Walmart website. Alternatively, you can also find info on VGA switch boxes from retailers such as Amazon.
Yes, you can install a dimmer switch on a 3-way lighting circuit by replacing one of the existing switches with a compatible dimmer switch designed for 3-way circuits.
a separate contact: single pole switches have one contact, double pole two, etc.throws in a switch are the number of ways the switch may be set.SPST - one contact that can only be turned on/off.SPDT - one contact that can be switched two ways.6P4T - six contacts that can be switched four ways, usually a rotary switch.etc.
Physically a multiplexer usually looks like a box of some sort. More important is what is inside. The inside of a multiplexer contains a switch or switches, a power supply, and the electronic circuits to manage the system. One link is to informative datasheets for a couple of multiplexer Integrated Circuits from which much can be learned about multiplexer characteristics. There are many, many more kinds of multiplexer ICs.
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.
Follow the instructions. I assume you are trying to switch 2 circuits with one switch. I always do a continuity test with an electrical meter to find which terminals to use. Usually one circuit will be wired on the left and one on the right.
You can find the starter relay switch in the fuse box. The starter relay switch will be one of the relay switch is in the third column. The exact location should be listed on the inside cover of the fuse box.
