1. Microswitch has three wiring pins which corresponding “COM” “NO” and “NC”
ports, among them, “COM” is common port, “NO” is normally open port, “NC” is
normally close port.
2. Use a multimeter to measure the resistance between “COM” pin and “NO” pin,
normally resistance is infinite, if it is 0, indicating microswitch is broken and
need to replace a new one; the resistance should be 0 when press metal sheet,
if it is infinite, indicating microswitch is broken and need to replace a new one.
