Allen-Bradley 800T-H48B is a 30 mm, two-position keyed rotary selector switch with cylinder lock for secured control in industrial panels. It uses left-side key removal (D018) and offers spring-return from the right position, delivering momentary action when released from that side. The device provides 2 normally open and 2 normally closed contacts (2NO-2NC) for wiring multiple control paths in one unit, enabling both actuation and status signaling. Designed for panel installations, this 800T-series selector supports locked operation to prevent accidental changes, making it a common choice for mode selection or start/stop circuits in automation equipment.
