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.

Abstract: This disclosure relates to various embodiments of lockout relay devices. In one embodiment, a lockout relay device may transition between a closed position and a lockout position in response to an action of a deck device. The lockout relay may further be configured to transition from the lockout position to the closed position only in response to one of a manual adjustment and a reset operation. A manual actuator may permit a manual transition of the lockout relay device from the closed position to the lockout position and from the lockout position to the closed position. A lockout mechanism may be configured to cause the lockout relay device to transition to the lockout position in response to the force generated by the deck device. The lockout relay device may remain in the lockout position until the occurrence of one of a manual adjustment and a reset operation.
