A switch gang is an independent control on the accessory. Switching ways describe how that control works in the circuit. A socket outlet or data port is a connection point. Faceplate and back-box format describe the physical installation, so these counts are not interchangeable.
Reading the terms on a schedule
Term | Meaning | Example |
|---|---|---|
Control gang | One independent switching control | Two rockers on AS304 |
Switching ways | Circuit switching arrangement | Two-way lighting control |
Outlet / port | An electrical or data connection | One Type G outlet on AS405 |
Plate / back-box format | Physical mounting dimensions | Square plate and required box depth |
For example, Admore AS304 has two rockers and two-way switching. Its two control gangs fit a square faceplate described as a one-gang plate format. The number of controls does not set the outside plate dimensions.
Two-way switching and socket outlets
Two-way switching supports control from two positions in a suitable circuit. It is a switching function, not a statement about the number of rockers or the size of the mounting box. Installation and circuit selection belong with a qualified electrician.
Admore AS405 is a 13A switched Type G power socket with one outlet and one local rocker. Its outlet count describes its function; its square plate and minimum box depth describe installation space.
Matching the accessory to the point
Write the function before the finish: a lighting switch, switched power outlet, data connection or blank plate. Then add the required number of controls/outlets/ports and the model’s physical dimensions.
- Lighting switch: control gangs, switching ways and electrical rating.
- Power socket: outlet type, number of outlets, current rating and any switching.
- Data outlet: connector type and port count, plus plate and back-box dimensions.
- All points: finish, model code, mounting format and minimum box depth.
Weatherproof accessories add enclosure requirements for the installation environment. Smart switches and sockets add network and control-system requirements.
Preparing an accessory BOQ
Use switches and sockets to identify the required functions, then keep each model and quantity on its own line. The BOQ guide gives a practical format. Send your point schedule with the selected finishes and installation requirements.
