Harsh Environment Snap-Acting Switches
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 switches can be pushed down by front-to-back movement, so they can be activated with pressure anywhere along their length.
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 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 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.

Mil. Spec. Washdown Snap-Acting Switches
Keep out dirt and moisture—the sealed housing on these switches is watertight and meet MIL-PRF-8805. They’re sized to fit in the tiniest of spaces. To minimize arcing and prevent contacts from sticking, they open and close circuits quickly. They’re often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.
Switches with a plunger actuator require a push to actuate.
Switches with a roller lever actuator allow parts to glide across the actuation surface with less friction than standard levers.

Enclosed Wet-Location Snap-Acting Switches
Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits in a snap—their quick actuation limits arcing and keeps contacts from sticking. These switches are often used to indicate an open appliance or enclosure door. 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 roller plunger actuator have a roller that moves parallel to the body length when an object pushes the actuator. This reduces friction to limit wear and tear on your switch.
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.
Switches with a 4-pole micro M12 plug quickly connect and disconnect from your switch. Use cables (sold separately) to wire your switch connection to your setup.

Ultra-Miniature Snap-Acting Switches
Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum. Because snap-acting switches 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.
Plunger actuator switches send a signal when the actuator is pushed directly downward. They have a small footprint, reducing the risk of accidental switching.
Lever actuator switches have a larger surface area than plunger actuator switches and can be pushed down by front-to-back movement, so they require less precision to activate.
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.
