ABSTRACT:
A push button member (10) is mounted to be moved longitudinally between a first position (FIG. 1A) and a second position (FIG. 1B). The push button member includes a cam surface (16) for selectively camming an electrical contact engaging surface (18) and a hold surface (48) past a follower member (32) as the push button member is moved from the first position to the second position. In the second position, the electrical contact engaging surface urges electrical leaf spring contacts (20) into a closed conducting relationship. The spring contacts remain in the conducting relationship until a radially greater extending cam surface (52) of a timing cam (50) engages the follower member moving it to the release position. In the release position, a spring (12) biases the push button member from the second position back to the first position allowing the electrical contacts to open.
