Saia-Burgess Micro Switch
The Saia-Burgess is a single pole single throw (SPST) normally closed microswitch. It is also known as a snap action switch. It operates by using a spring-loaded lever to open and close a set of internal contacts inside the unit. It has a simulated roller lever actuator. It requires a 5N operating force to energize the spring. The operating current rating is 10A.
