This 3 position automatic door key switch lets authorised staff set how an automatic door operates with a simple turn of the key. Choose Auto for normal automatic opening, Hold Open to keep the door open for deliveries, busy periods or cleaning, and Off to shut the door down at closing time. Only people with a key can change the mode, so customers and visitors cannot interfere with the door settings.
The switch has an engraved Hold Open / Off / Auto faceplate, so the selected mode is always clear. It comes fitted in a black ABS surface back box, ready to mount on a wall, frame or post next to the door, and is supplied with 2 keys.
Why choose this 3 position automatic door key switch?
- Three clear door modes: Hold Open, Off and Auto in one compact switch.
- Key-operated security: only key holders can change how the door works.
- Engraved legend plate: Hold Open / Off / Auto markings that will not wear off like stickers.
- Surface back box included: black ABS box for quick surface mounting – no chasing walls.
- Slim 44 x 115mm plate: fits narrow frames and tight spaces beside the door.
- 2 keys supplied: one for daily use and a spare.
- Great value: a reliable replacement program selector at a trade-friendly price.
Where is a door mode key switch used?
- Automatic sliding doors in shops, supermarkets and shopping centres
- Automatic swing doors in offices, hospitals and care homes

This 3 position automatic door key switch is a popular replacement when an old program switch has failed, the keys have been lost, or a door has been fitted without a key-operated mode selector. For guidance on the safety of powered pedestrian doors, see the HSE safety bulletin on powered doors.
How does a 3 position automatic door key switch work?
The switch connects to the program or mode selector terminals on your automatic door control unit. Turning the key changes which contacts are made, and the door operator responds by switching between its operating modes:
- Auto – the door opens and closes automatically using its sensors.
- Hold Open – the door stays open until the mode is changed.
- Off – the operator stops automatic opening, typically at the end of the day.
Exact behaviour in each mode depends on the door operator and how it is configured. A wiring diagram is available on request – just message us with your door operator model.

Installation
Isolate the power to the door operator before fitting. Fix the back box in a convenient position near the door, run the cable from the door control unit and connect it to the switch following the operator manufacturer’s wiring instructions for the program selector. Test all three modes before handing the door back into service. Automatic door work should be carried out by a competent installer.
