Draper Switch with Locking Cover Plate SP-KPS-1

The SP-KPS-1 pairs a standard Draper wall switch with a hinged, key-locking cover plate - the switch itself is a normal rocker control, but the plate locks over it so the screen can't be operated unless someone unlocks the cover first.

It's a lower-cost alternative to a full key-operated switch (KS-1/KS-3) when the goal is simply to keep the switch from being bumped or used casually between authorized sessions.
