Allen‑Bradley 800T-H4A is a 30 mm two‑position selector switch from the 800T family that is non‑illuminated and designed for simple two‑state control in industrial equipment. It provides one normally open (NO) and one normally closed (NC) contact, offering a minimal single‑pole, two‑output configuration. The unit features a white insert and a standard knob, with spring return from the left when released, making it suitable for applications where the handle must return to a defined position after actuation. The catalog number 800T‑H4A is commonly used in control panels to select between two operating states, enabling straightforward status or mode selection in machines and processes.
