16 mm Panel-Mount Key Switches
Limit access to sensitive equipment—these switches require a key to actuate. Rated NEMA 4, 13, and IP65, they're protected from washdowns and oil/coolant spraying. All are keyed alike, so they open with the same key.
Mounting wrenches (sold separately) make it easier to install switches in crowded panels.
