The Blodgett 5906 Micro Switch 20A controls electrical circuits by opening or closing connections based on mechanical movement used in commercial systems. Rated for 20 amps, this switch activates when a lever or actuator is engaged, allowing or interrupting current flow to connected components. It works by using an internal spring-loaded mechanism that responds to physical contact, triggering rapid switching action. This process allows precise control of electrical functions such as door position or component activation. Its design supports accurate circuit response and consistent electrical operation during equipment use.
