ABSTRACT:
A combination actuator and guard for palm switches of the type conventionally used to initiate the cycle operation of hydraulic presses and like machines comprising a hand-lever pivotally mounted on a frame that is adapted for mounting on the machine at the cycle control switch position with the lever superimposed on the palm switch and including a slidable latch member on the hand-lever normally spring-loaded to engage stop means on the frame to prevent operation of the hand-lever to actuate the switch but moveable by an actuator at the pivoted edge of the hand-lever to release the stop means and permit manipulation of the hand-lever to actuate the palm switch and initiate the machine cycle.
