Dual action switch assembly with sequentially actuated membrane switches including a reciprocating circuit board

摘要

A two-way dual action electric switch assembly has an actuator that slides in housing from a neutral position to a first position to a second position and back to the neutral position in each direction. Travelling circuit boards are slideably disposed in the housing on either side of the actuator and a single elastomeric dome switch is disposed between the actuator and each travelling circuit board. A fixed circuit board is outboard of each travelling circuit board and a pair of second elastomeric dome switches are disposed between each travelling circuit board and its associated fixed outboard circuit board. The single elastomeric dome switches close electric circuitry of the travelling circuit boards in the first positions and the pairs of second elastomeric dome switches close electric circuitry of the fixed outboard circuit boards in the second positions.
