Open and close circuits quickly to minimize arcing and prevent contacts from sticking. These switches are often used as door-open indicators on appliances and enclosures or as an internal component in limit, pressure, and temperature switches.
Plastic covers (sold separately) are compatible with switches with screw terminals. They fit over the bottom of the switch to prevent contact with live terminals.

Precision Subminiature Snap-Acting Switches
Plunger
Lever
Roller Lever
Actuate these switches with a fraction of the force of other subminiature switches for increased accuracy. Among the smallest snap-acting switches we offer, they fit into 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.
