Snap-Acting Switches
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.
