Allen-Bradley 800T-H17D1 Selector Switch Maintained Lever

Allen-Bradley 800T-H17D1 is a 30 mm diameter, two‑position selector switch from the 800T family that uses a maintained lever to hold a chosen state. The operator features a white knob insert and provides a single normally open (1 NO) contact in its standard configuration, with the unit configured as non‑illuminated for panel mounting in industrial control applications. This front‑panel switch is designed for simple on/off or two‑state control schemes in equipment such as conveyors, packaging lines, and automated production cells, where the position must stay in place until manually changed. The 800T-H17D1 is compatible with the 800T contact‑block ecosystem and is typically paired with standard cams for reliable actuation, using a knob‑lever operator to deliver clear tactile feedback in demanding environments. When wiring, select the appropriate contact block suffix to match your control logic, and ensure proper mounting hardware for a secure installation. Identified by the H17D1 suffix, this 2‑position maintained variant provides a straightforward, durable manual input option for control panels requiring a single NO path and a retained position until the operator moves it again.
