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.
