The Industrial Key Switch (KSW) is a single-zone wall-mounted user interface that provides local on/off control over a lighting zone. Utilizing a standard single-gang junction box form factor in a rugged stainless steel housing, the KSW connects to the Encelium X Light Management System through a Sensor Interface Module (SIM).

For damp-rated applications a damp-rated SIM is available. Examples of this type of environment may include basements, above-ground parking garages, barns, and cold-storage warehouses as well as partially protected locations under canopies, marquees, and roofed open porches.
