OP and LN Series Enclosed Basic Switches
LN switches can withstand rapid hammer-blow actuation because impact on the
actuating plunger cannot reach the precision switch unit inside. Individual seals
around each leadwire and cover plate protect the switch cavity from condensation,
oil, and dust. OP enclosed switches are precision snap-action switches sealed in
rugged cast-aluminum housings. The cover and shaft seals keep out moisture and
contaminants on rotary-operated switches.
