A two-pole make-before-break switch includes a base housing, a cover member secured to the base housing, an actuating member disposed above the cover member, and first and second contact assemblies mounted on an interior portion of the base housing. The first contact assembly includes a normally-open common contact blade member that is closed prior to the closing of another set of normally-open contacts with a snap action in a second contact assembly so as to complete an electrical connection. The switch is operable by depressing the actuator member either in a first direction to effect a manual-up mode of operation or in a second direction to effect down modes of operation.

Two-pole make-before-break switch

A direct connection for printed circuit boards where a primary board has a slot therethrough with slight edge projections which control the width of the slot to close tolerances. Spaced parallel conductive strips on the surfaces of the primary board terminate at the slot. A secondary board has an insert portion sized and configured for insertion into the slot in a close fit with the edge projections to maintain the boards mutually perpendicular. Spaced parallel strips on the insert are disposed adjacent the termination of the primary board strip. The strips are interconnected by soldering to provide direct circuit interconnection between the primary and secondary boards.
