ABSTRACT:
A microdevice in the form of an electrical switch. A microdevice for providing switching at a high repetition rate, including a cell divided into two chambers by a bistable movable membrane. A charge of gas in the cell and a source for directly heating the gas to increase the gas pressure and move the membrane, the source for heating including a pulsed source for generating transient gas pressure increases, with the cell including an arrangement for cooling the gas for reducing the gas pressure after an increase.
