I can't find those high amperage microswitches that all the nerf modders use. I prefer one that won't take to long to ship.

Thanks.

If you don't want to be constrained by available switch options then what you need is a relay that has a coil compatible with the operating voltage range of your circuit. The relay contacts will handle the high amperage circuit, while your lower amperage rating switch will only need to handle the wattage of the coil for the relay.

 

This leaves the available options for your trigger switch wide open.

The little critters of nature, they don't know that they're ugly. That's very funny, a fly marrying a bumble bee. I told you I'd shoot, but you didn't believe me. Why didn't you believe me?

Im just trying to find the ones that are black and red and have the rollers at the end, I'm still running those 2 xp180's on 3 trustfires (which i know they suck) I'm going to buy the third one when i find the switches and battery i need.

Maybe try asking your local Microcenter or other hobby electronics shop. They might have some switches.

 

 

RadioShack would for sure have this stuff, but it's gone now.

(RIP RadioShack, you will be remembered fondly ;-; )

Don't you just love it when you FINALLY finish that build you've been working on?

And then something breaks?

 

Fun.

I still have 2 radioshacks nearby me. I'm not sure about a hobby store though.

Lucky. I don't mean actual HOBBY STORE, I mean a store that carries hobby-style electronics. Radio Shack carried things like Arduinos (where I got my first two), Servo motors, LEDs, and I'm sure high-current switches and high-performance motors as well. Microcenter is the next best thing, but the closest one for me is still pretty darn far unfortunately.

Uxcell a13060600ux0523 16 Amp 4 Amp 250VAC 1NO+1NC Screw Connector Actuator Limit Micro Switch (5 Piece) https://www.amazon.c...a_dyKGxbNGS9HAX. These are the non roller version of those switches your looking for.

But if you can't find then CaptainSlug's relay trick works great for the application

Why are you using a 3s and xp180s?

I'm just a nerd with Asperger's Syndrome and a few electronics.

Because one should always use a margin of safety.  You wouldn't want to burn out the switch,right?
