Allen-Bradley 800T-H2 2-Position Rotary Maintained Selector Switch

Allen-Bradley 800T-H2 is a two-position rotary selector switch with a knob operator, part of the 800T family. This maintained switch provides two distinct positions and uses a contact block configured as two normally open (NO) contacts and one normally closed (NC) contact, enabling straightforward control logic in industrial panels. The maintained action latches in the selected detent until the operator rotates the knob to the other position, making it well-suited for mode selection, on/off control schemes, or gating functions in automation circuits where a stable, manual input is required. The catalog number 800T-H2 identifies this specific two-position arrangement within Allen-Bradley’s rotary switch lineup. With a knob actuator, it offers positive tactile feedback during operation and clear indication of the active position through the mechanical detents, which helps operators verify the switch state at a glance. This configuration supports wiring to two NO circuits and one NC connection, providing flexibility for controlling related relays or logic circuits in a wide range of industrial applications.
