Manual-Reset Safety Limit Switches


Style A	Style B	Style C

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated. Pull the knob to reset. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. These switches send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects.

Rated IP67, these switches seal out water if they’re washed down or briefly submersed.

Style B—Style B have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction.

Style C—Style C have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction. You can also adjust the actuator's height, making it easier to align the switch with the target during installation.

Tilt Switches


Style A	Style B	Style C

Style D	Style E

Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. All combine electromechanical and solid state technologies for reliability and long life.

Differential Angle—Differential angle is the total angle from the point of activation to the point of deactivation.
