Hi guys. I have a quick question. I'm building a project with a 24V DC power supply, however I want there to be an ON/OFF switch (obviously). But I want to do this with a VERY small switch and relay. However, I can't seem to find a good way to implement this.
I need to use a very small contact switch to control a relay which controls power to 4 motors at 3 amps a piece and some other small things, but I only have 24V DC power. Most if not all small switches can't handle 24V DC. How can I get around this? Could I build a small voltage converter? Maybe using a small MOSFET transistor? Since the relay would only draw very little amps could a MOSFET handle a large voltage drop? Say to 5v or less?
Thanks!
