The KWA KM4 Trigger Switch is Part 58. This is the main body of the trigger switch only. The metal contact and pin are not included, but can be swapped from the original trigger switch. This is ideal for a damaged switch that does not function in semi-auto. Replacing a damaged trigger switch can restore semi-auto function.
