Abstract
A micro-electromechanical actuating mechanism includes a substrate. Integrated circuitry is positioned on the substrate and includes drive circuitry. An actuator is arranged on the substrate to be electrically connected to the drive circuitry and is reciprocally displaceable with respect to the substrate on receipt of a current pulse from the drive circuitry. The actuator and the integrated circuitry define a test circuit. A switch assembly is arranged on the actuator and the substrate to be incorporated in the test circuit so that the switch assembly closes the test circuit when the actuator is displaced a predetermined extent.
