Drill battery Switch Answered

Hello! i got a car horn with an motor, the motor is rated 12 Volts so i got a 12 volt drill battery since im not going to install it on a car. However, i got a problem... My plan is to mount 2 switches, a Keyswitch and a push buttom switch. so i bough that .. However it made me think if the small switches can take the Power of the drill batt.

I have no idea how many AMps a drill batt got, and the key switch is rated 0,5A / 250 VAC and i the push/switch one is a standart like this https://elextra.dk/images/large/8011.jpg


.. Now do you think i need a other switch or will i smelt them by pluggin the Drill batt on ?

As far as the switch is concerned it doesn't matter how many amps the battery offers but how many amps the motor draws. You also nee to know how many amps the motor draws so you can be sure your not going to draw more amps then the battery can handle.

A switch that can handle 250VAC at .5A can handle 125W. So at 12V it should be able to handle 10A. If the motor needs that much power then i'm afraid the 12V drill battery may not work too well or could melt down from being discharged too fast.

Hello there, thanks for your fast answer.. I tried hooking the battery up to the motor with 2 wires, it sounds perfect. so the battery Works well with the motor.. My problem is the switch.

Do you think the switches can handle it? and what happends if it cant. Will it break or will it just let less power go though it?


Sorry for my bad english :s

If the switch can't handle it it will get very hot. But like i said any 250VAC .5A switch can easily handle 12VDC @ 10A. The motor shouldn't be putting that much power.

So it wont slow down the power if that can be said?

Like i tried running the power though a very small wire and it didnt work.

Thanks
