Snap action switches are mechanical switches that produce a very rapid transfer of contacts from one position to another.

Switches are devices that allow electric current to flow when closed and prevent current flow when opened.

Foot switches are switches that are activated by a pedal or air bulb (bellows

Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes.

Dry material (powders) level switches are used to measure levels of dry, solid materials via an electrical switching action

Temperature instruments use contact or noncontact methods to measure temperature.

Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions
