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 have the capability to withstand and control the pressure of an internal explosion and can rapidly cool the explosive temperature. These limit switches are generally used in control valves and actuators, petroleum plants, chemical plants, waste treatment, and hazardous waste handling.

LSXA3K Limit Switch from Honeywell is an explosion-proof device, specially designed for use in hazardous atmospheres. It comes with captive head, body screws and field adjustable operating modes for reduced inventory. This Honeywell switch features tracking interchangeability with micro switch ML-E1 and HDLS and comes with a variety of heads and non-sparking actuators.
