Overview

MICRO SWITCH LSX Series Explosion-Proof Limit Switches (Non Plug-in), Side Rotary, 1NC 1NO SPDT Snap Action, 0.5 in - 14NPT conduit, Lever Included.
MICRO SWITCH LSX switches are for use either indoors or outdoors in hazardous atmospheres as they are a completely sealed, explosion-proof device. Mounting hole location and tracking is the same as the long established MICRO SWITCH ™ ML-E1 explosion-proof switch. An optional mounting plate provides the same tracking and mounting as the standard HDLS. The majority of HDLS operating heads and circuitry options are available on the LSX. Standard HDLS levers are used, but because of explosion-proof requirements, only nylon rollers or other non-sparking material can be selected. Plunger and cat whisker types listed in the LSX order guide are non-sparking materials. The MICRO SWITCH LSX withstands pressure of an internal explosion and cools the exploding gases below the kindling temperature of the explosive atmosphere. Flame paths are provided by the cover-housing threads and an extended plunger between the switch cavity and head.
