These switches are a common failure point on the Hobbywing Fusion systems. In my particular case, I bought this switch, installed it correctly, and only got about ten minutes of time before the replacement switch died as well. The system continued functioning, but the switch died in a permanently "on" state. It's possible there is a deeper problem with my Fusion system that is causing the switches to go bad, but it's hard to say for certain.

If You own an Old version Fusion SE with BLACK print on the power logo buy this immediately! I had 2 in a row defects they twitched violently when powered off if drag brake was set above a 2, They sometimes wouldn’t power off without pulling plug. They also cut out and powered off on full throttle. The 2nd one actually caught fire after a cutout and destroyed my NEW H10 Optic ! The motor itself survived albeit smokey I soldered on this upgraded switch and its flawless! Hobbywing should just admit this openly but obviously won’t! Before you loose your rc to a fire buy this ! I will be ordering a bunch to replace my others !
