Snap-Acting Switches
Open and close circuits in a snap. These switches actuate quickly to minimize arcing and prevent contacts from sticking. They’re often used to indicate that an appliance or enclosure door is open. You can also use them inside limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a lever actuator have an arm that extends to give them a larger actuation area than switches with a plunger actuator.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
Plastic covers (sold separately) are compatible with switches with screw terminals. They fit over the bottom of the switch to prevent contact with live terminals.
