Limit Switches are generally used to control machinery in industrial applications. They act as a safety interlock and can be used to establish or disrupt electrical connections. The LSX micro switches are designed to withstand pressure during an internal explosion and cools the exploding gases below the kindling temperature of the explosive atmosphere. These limit switches are for use either indoors or outdoors in hazardous atmospheres as they are a completely sealed, explosion-proof device and are therefore often used in control valves and actuators, petroleum plants, chemical plants, waste treatment and hazardous waste handling.

LSXYAB3K Limit Switch from Honeywell offers a variety of heads and non-sparkling actuators. This Honeywell switch comes with an internal grounding screw and a choice of silver or gold contacts.
