Tonight, I removed and opened the factory microswitch (made by XURUI, XV-152-1C25, 20A, 125/250VAC) . It's a piece of crap!
First of all, the plastic casing is not heat resistant. The contacts are not made of copper, only copper coated. I discovered serious burning marks, down to the bare metal. I repaired the switch (temporarily, until better replacement) and installed an extra part to reduce spark formation.
I also inspected the hop-up, it's dog eared after 5K rounds. Any recommended brand for replacement?
