ABSTRACT:
A switch actuator assembly is provided comprising a circuit board housing including an upper housing and a lower housing forming a board compartment. A circuit board assembly, mounted within the board compartment, includes a switch element. A button assembly, positioned remotely from the upper housing, includes a cantilever button element. A plunger array assembly is included comprising a plunger array frame and a plunger element. The plunger element comprises a main plunger piston having a first plunger end configured to engage the cantilever button element only in a radial direction and a second plunger end configured to transfer force to the switch element. A plunger cantilever arm has a first cantilever end affixed to the plunger array frame and a second cantilever end affixed to the main plunger piston and is mounted in a mount position configured to minimize horizontal displacement of said second plunger end.
