Ceiling pull-cord switch plan mark
Plan mark for a ceiling-mounted switch operated by a hanging cord, common in bathrooms and accessible toilets.
In plain English
What does Ceiling pull-cord switch plan mark mean?
A ceiling pull-cord switch is a one-way or two-pole switch fixed to the ceiling and operated by a cord. The plan mark adds a short line with a small arrow or cord end to the switch symbol, telling the reader that the device sits at ceiling level and is operated from below.
A simple example
These switches are used in bathrooms where a wall switch would be in a restricted zone, and in accessible toilets where the cord forms part of an assistance call system. The plan should distinguish a light-switching pull cord from an emergency assistance pull cord, which is a different device.
What the drawings help you do
The plan mark does not give the cord length or ceiling fixing detail. Those come from the specification and accessibility requirements.
This particular reference

What it represents
A ceiling pull-cord switch is a one-way or two-pole switch fixed to the ceiling and operated by a cord. The plan mark adds a short line with a small arrow or cord end to the switch symbol, telling the reader that the device sits at ceiling level and is operated from below.
These switches are used in bathrooms where a wall switch would be in a restricted zone, and in accessible toilets where the cord forms part of an assistance call system. The plan should distinguish a light-switching pull cord from an emergency assistance pull cord, which is a different device.
The plan mark does not give the cord length or ceiling fixing detail. Those come from the specification and accessibility requirements.
How to read it
- Check whether the cord switches lights, a fan or an assistance call.
- Note that this is a building plan mark; schematic pull-cord switches in machine controls are a different device.
Information to show or reference
- State switch rating and pole count.
- Distinguish from assistance-call pull cords.
- Give cord length or end height.
A distinction that matters
The schematic pull-cord switch in control circuits is a machine emergency device; this plan mark is a building lighting accessory.
