Snap Action & Limit Switches

Snap action switches and limit switches are electronic switches that are commonly used in industrial control systems and other applications that require precise and reliable control of mechanical processes.

Snap action switches, also known as micro switches, are electrical switches that use a spring-loaded lever to activate the switch when a certain force or pressure is applied. They are commonly used in applications where a small and precise switch is needed, such as in appliances, vending machines, and automotive control systems.

Limit switches, on the other hand, are electrical switches that are activated when a moving object, such as a conveyor belt or door, reaches a specific position or limit. They are commonly used in industrial control systems to monitor the position of mechanical components and to prevent damage or accidents caused by overrunning or overshooting.

Both snap action switches and limit switches come in a variety of configurations, including normally open or normally closed switches, and can be wired to operate in a variety of ways, such as momentary or latching operation.
