ABSTRACT:
An apparatus for testing a switch is provided that permits the performance of a switch to be reliably tested and to precisely determine a host of parameters that collectively define the performance of the switch. The apparatus includes a stage upon which the switch is mounted. The apparatus also includes an actuator for actuating the switch and a positioning device, such as a micrometer, for controllably positioning at least one of the actuator and the stage such that the actuator actuates the switch. The apparatus may also include a measurement device for monitoring the electrical condition of the switch as its state is altered. For example, the measurement device may monitor a measure representative of the electrical resistance such as voltage drop across at least two contacts of the switch. Additionally, the measurement device may monitor travel of at least one of the actuator and the stage.
