Title: Where to find this microswitch?
Post by: acevedor2 on September 05, 2009, 10:29:08 pm

Hey guys - This microswitch is our of the gun on my zombie raid.  I know it's toast, I just don't know where to find one like it.  Any ideas?  Thanks!
Cheers

Thanks.  I just hope they don't have a minimum order...  Since I only need 2 :)

Thanks again!
Cheers.

It probably would you just have to get the right shape and have the right little arm on there.

There's a little more to it than the dimensions, but if you just want it to work (ignoring the feel), then it's not too hard to find a replacement.  If you have the part number off the original, you might be able to find a spec sheet online somewhere.  Different switches have different actuation forces as well as a different MTBF.

I have some LS-30's that one switch failed on.  I couldn't find the exact same switch, but I spoke to Mouser or DigiKey (can't remember which) and they worked with me to find a replacement of the same specs.

Oh, one more thing.  If you can't find a lever arm that's exactly the right length, you can always get one that's a bit longer and cut it to the right dimensions.

Good luck!
