ABSTRACT:
A housing 10, 12 includes a slide chamber 14 in which a slide bar 30 reciprocates between three positions. A coil spring 60 is carried by the bar and extends into lower and upper recesses 50, 52 in the housing. When the bar is reciprocated from the intermediate position to either of the other positions, the ends of the recesses 54 compress the spring, thereby biasing the bar into the intermediate position.
