Allen-Bradley 800T-H48B is a 30.5 mm two-position cylinder-lock selector switch with a spring-return actuator and a D018 key code. It provides a 2NO-2NC contact configuration via integrated contact blocks, enabling both normally open and normally closed circuits for control and safety interlock applications in industrial panels. As a member of the 800T family, it is designed for rugged machine environments and accepts standard 800T contact blocks for expanding functionality. The unit uses a keyed operation that allows one key removal to secure access during servicing and prevent inadvertent actuation.
