Will a 120V switch work with 12v?
Will a 120V switch work with 12v?
A 120V switch may not have the current capacity for a 12v circuit. Typical wall switches are for 15 or 20 amps, and 12v circuits can be 30 or 50A. Since AC current is oscillating, you don’t get 100% current the way you do with DC, so carrying DC on an AC rated switch also needs derating.
Can you use AC toggle switch on DC?
Yes, an AC switch should be fine to control a few milliamperes of a relay coil. The relay is designed to switch high DC currents.
Can you use a 12V switch for 5v?
Probably. You need to find out the current that the relay coil needs when it is fed at 5 volts. Then you need a resistor that will drop, lose. the extra voltage difference between the 12 to 5 volts.
How to connect toggle switch?
1) Defer to the instructions provided with your switch or your device. 2) Cut the supply wire in your device. For your toggle switch to function as an on-off switch, you’ll need to wire your toggle switch to the device’s power supply. 3) Add a pigtail if either end of the wire does not reach the switch. 4) Connect the supply wire to the toggle switch. At this point, you’ve made a break in the device’s supply wire, you’ll need to add your toggle switch in the 5) Test your switch. When your toggle switch is wired properly, carefully reconnect the device’s power supply and test the function of the toggle switch.
How to wire a 3 way light switch?
– When wiring a 3-way switch, first screw the terminal screws of the new switch until they are difficult to turn. – Connect the ground wire to the green screw. – Connect the wire marked common to the black or dark colored screw. – Connect the two remaining traveler wires to the two brass or light colored screws. – Connect the wires to screw terminals by slipping the looped wire under the head of the screw. The end of the loop should point clockwise. – Use long nose pliers to squeeze the wire end tight around the screw. – Tighten the terminal screws.
Can a 3 way switch be used in place of a single pole switch?
Yes it can work. 3-way switches are spdt (single pole double throw) with 3 screw terminals, and regular switches are spst (single pole single throw) with 2 screw terminals. Just pick the correct two contacts and you are good to go.
How do you wire light with two switches?
Connect the black wire coming from the lightbox with the black wire leading to the second switch by twisting their ends together and fastening with a third wire nut. Connect the 2 ground wires with a fourth wire nut. Take the white wire leading to the second box and mark its end black too.
