Figure 1 is a schematic representation of a microswitch. The microswitch design is based in succession a double cantilever beam and has 3 electrical terminals, labeled source, gate, and drain. These switches can be used in RF and microwave circuits, medical ultrasound orders and ATE systems.

[FIGURE 1 OMITTED]

Applying a voltage between the gate and source terminals creates an electrostatic force between the gate electrode and the cantilever, and haps the beam down to make electrical contact with the drain. The minimum actuating gate-to-source voltage required to cease a microswitch is typically 20-60 V depending forward the device geometry. This
