Abstract
A switch with an actuator has two supporting columns on a substrate, and a rocking plate on the supporting columns. The rocking plate is pivoted by (pivotally mounted on) the two supporting columns. The rocking plate is made of conductive material, so that it can be subjected to electrostatic force of an adsorption electrode. In the switch, it is not necessary to provide a narrow beam to support the rocking plate, because the rocking plate is pivoted by the supporting columns. Therefore, the switch is a long-life microswitch.
