Safety Interlock Switch Assembly
The BLDC motor controller requires a constant closed-loop signal from the handle safety switches to maintain the PWM output to the motor. Mechanical fatigue in the interlock switch or internal spring failure causes the circuit to open during operation, specifically when vibration is present. Replacing the switch assembly restores the integrity of the safety loop, preventing the controller from initiating an emergency motor stall.
