Harsh Environment Snap-Acting Switches
With a rubber-encased housing and stainless steel bracket, these switches resist vibration and corrosion. They’re rated IP68 for protection from dust and temporary submersion. 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.

Level Switches for Dry Materials
When dry material rises to the level of the rotating paddle, these switches actuate. All are rated NEMA 4X and IP66 for protection from corrosion and washdowns.
Switches with auxiliary SPDT relay activate an alarm (not included).
