Snap action limit switches are mechanical devices that make or break an electrical connection by the closing or opening electrical contacts or solid state circuitry when actuated by human or mechanical interaction most commonly at a travel limit position. Limit switches are selected by actuator types such as an adjustable plunger or rod, toggle, arm lever, roller, cone, leaf, rotary actuator, spring, whisker or cable.
