Open and close circuits in a snap—even in harsh conditions. With a rubber-encased housing and stainless steel bracket, these switches handle high vibrations and resist corrosion. They’re rated IP68 for protection from dust and temporary submersion. Because they open and close circuits faster than other switches—reducing the time that contacts are near one another—they prevent contacts from sticking. They also minimize the chance of arcing, so electricity won’t jump across contacts. They’re often used as door-open indicators on enclosures or as an internal component in limit, pressure, and temperature switches.
Lever Actuator Style—Lever actuator switches can be pushed down by front-to-back movement, so they can be activated with pressure anywhere along their length.
Roller Lever Actuator Style—Roller lever actuator switches activate when parts glide front-to-back across their actuation surface. They produce less friction than standard levers, which prevents wear and tear over time.
Simulated Roller Lever Actuator Style—Simulated roller lever actuator switches have a curved arm that can be pressed down for actuation by forward, backward, and repeated back-and-forth movement.
Dual Switch Roller Lever Actuator Style—Dual switch roller lever actuator switches actuate two SPDT switches simultaneously, giving you the equivalent of a DPDT switch. A roller at the end of the arm reduces friction and wear from parts moving across their actuation surface.
