Hello. I've never really worked with relays before, so I was hoping for some guidance.
My project is a battery powered robot with a single motor that pulls about 5 or 6 amps. I want to use a power switch that is very small and rated for less than an amp.
The top image is what I'm working with now. 12v Lipo Battery which runs through a switch which goes into my microcontroller/mosfets/etc.
Can I switch this out for something like the bottom image? Where the batteries are hooked up directly to the switch AND relay. SO I can just hit the low-rated power switch and the relay completes the circuit? Where even if the motor is pulling 6 amps and the switch is only rated for say 500mah, it wont get fried?
If this is correct, can you recommend the most compact solution for the relay? One thing I lack is space for a large component in terms of height, which is what I see a lot of relays looking like. I can do long and flat. But Tall is tough.
Any help is very appreciated!
