Electrical snap action switches operate on the arched elastic sheetmetal member principle, and provide snap actions in response to changes in pressure exerted upon the arch. A conventional snap action switch conducts upon mechanical contact between a metal snap action plate and metal pins (or conductors on a printed circuit board). In such a snap action switch, switch closure is recognized by detecting an electrical short between pins. Pneumatic snap action switches have a diaphragm and two or more electrical contacts arranged inside the switch body and sealed by the diaphragm so that upon a particular pressure being applied the internal contacts close and the switch performs its desired function. A subminiature snap action switch is characterized by an actuator lever which causes a coil spring in a pivot bracket assembly to open or close a pair of electrical contacts. Single pole snap action dome or oil can switches have been used to provide reliable electrical switch contacts in relatively low-current apparatus, for example electronic calculators or computers. Such switches have typically utilized a dome-shaped switch element to make and break electrical contact with an associated underlying conducting contact.
