Can you use normal light switch for 12V?
Yes , a standard household light switch will work on 12V if wired correctly,but it sounds like you hooked both wires from the battery to the switch!!
How does a 12V switch work?
The standard 12V switch we are using to control lights from one location is a “Single Pole Single Throw”, or commonly abbreviated “SPST”. The switch simply ‘breaks’ or ‘connects’ the positive wire in the system allowing the power to either flow or not flow depending on if the switch is pushed or not.
Can you use 240v switch for 12 volt?
When used at a voltage lower than 240VAC, the switch can still handle at least 10A. In fact, at lower voltages it can probably handle more than 10A. Good luck with finding the actual current rating at 12VAC, but since you don’t need to switch more than 10A you don’t need to worry about that.
Can you run 12V through a 120V switch?
Unfortunately, you will not be able to use a 12v switch to replace a 120v switch. As you saw above, a switch has a maximum voltage rating that indicates what maximum values it can handle. Exceeding these values will inevitably cause the switch to fail.
Can you use AC switches for DC?
DC does not so the switch has to survive until the arc dies down on its own. So the DC switch has to be hardier and will therefore work with AC. However, the AC switch is not as hardy and should not be used with DC.
Is there a difference between an AC switch and a DC switch?
With dc, you’ve got a steady current in one direction, whereas with ac, both the magnitude and direction of the current change.
How many wires can be on a switch?
Three wires will be attached to your switch: a hot (black) wire, a neutral (white) wire and a ground (copper) wire. The black and white wires are attached using brass screws.
What size wire do I need for 10 amps?
For a maximum of 10 amps, you’ll need a wire gauge of 16.
