Abstract

An apparatus and method for testing a switch having an actuating plunger, the switch undergoing a switch event in response to the actuation of the actuating plunger includes a switch nest and clamp assembly for holding the switch at a precise and predetermined location and a motor driven plunger actuator for applying force to the plunger thereby to actuate the switch. The switch test station further includes a pressure sensor coupled to the plunger actuator which measures the force being applied to the plunger during switch actuation. An electrical sensor couples to the switch nest and measures the electrical characteristics of the switch while a microcomputer responsive to the pressure sensor and the electrical sensor determines the mechanical displacement of the actuating plunger at a switch event.
