ABSTRACT:
A deadman switch arrangement for a hedge trimmer wherein the auxiliary handle of the hedge trimmer is provided with a cover member which pivots thereon. The cover member has a camming surface near its pivot point, the camming surface having a ramp which moves an actuating pin inwardly toward the center of the hedge trimmer housing as the cover member is moved toward the auxiliary handle. When moved inwardly of the housing, the actuating pin closes a switch to complete the main power circuit of the hedge trimmer. The cover member is biased away from the auxiliary handle so that if the operator releases the cover member, the hedge trimmer is automatically turned off.
