Harsh Environment Snap-Acting Switches
 |  |
Style D | Style E |
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.
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.
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.

Enclosed Snap-Acting Switches
 |
Style F |
Enclosures protect these snap-acting switches from the environment. They open and close circuits quickly to minimize arcing and prevent contacts from sticking. 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 roller plunger, cross roller plunger, or roller lever actuator allow parts to glide across the actuation surface with less friction than standard plungers or levers. This prevents wear and tear over time.
