Abstract:
Systems and methods are disclosed herein relating to a momentary contact switch that can be both manually and electronically actuated. In some embodiments, an electronic module can be added to a manual momentary contact switch to enable electronic control. The momentary contact switch can be transitioned between first, second, and third electrical states based on the rotation of a shaft between first, second, and third rotational positions. Rotary arms are selectively engaged by pull arms connected to a master solenoid to selectively rotate the shaft from the first rotational position to the second and third rotational positions.
