Limit Switches

Limit switches are useful in a wide range of presence sensing applications including those in harsh environments due to their ease of installation, reliable operation, and rugged design. Limit switches are typically used in physical contact applications that can cause wear and tear on the switch actuator and electrical contacts, so exceeding two operations per second should be avoided. When selecting a limit switch, consider the application and actuation method first, as often they are the clearer determining factors. Limit switches are available in a variety of configurations, including the style of the actuator, type of movement, and object travel orientation.
