BG Metal Clad 7 Gang Intermediate Light Switch Custom Grid
An intermediate switch is used as the middle switch when one light is operated from three or more locations, such as the top and bottom of the stairs plus the landing, or either end of a long hallway. The Metal Clad range from BG is built for commercial and industrial installations, where a domestic finish would not withstand daily wear.
Please note: This switch will come in a grid format and requires simple clip-in assembly during installation.
You will be sent the following parts, all supplied by BG:
- 1x 6 & 8 Gang Flush Mounting Metal Back Box — MC503
- 2x 3 & 4 Gang Grid Yoke Frame — RFR34
- 1x 8 Gang Cover Plate — RMC8
- 7x Intermediate Switch — R13
- 1x Blank Grid Insert — RBLNK
Metal Clad front plates from BG are manufactured in heavy gauge steel and finished with epoxy powder coating, fitted with an earth terminal for extra safety. Suitable for flush wall mounting, or surface mount with metal clad boxes.
No visible plastic around switches. Colour matched screws for a sleek appearance. Captive backed out terminal screws for fast installation. Modern slim profile. 20A single pole.
Your grid switch arrives as a kit: a front plate, a metal grid frame and the switch modules you chose. Modules clip into the frame, the frame screws to the back box, and the plate fits over the top.
Safety first: Only fit this yourself if you are competent to do electrical work. Work must meet BS 7671, and some jobs (for example new circuits, or work in bathrooms) are notifiable under Part P in England and Wales. If in doubt, use a registered electrician.
- Switch the circuit off at the consumer unit and confirm it is dead with a voltage tester before touching any wiring.
- Unscrew the old switch, take a photo of the wiring and label which cable goes to which terminal.
- Check the back box is deep enough: at least 25 mm for switches, 35 mm for dimmers and larger plates (see the spec sheets below).
- Clip each module into the grid frame from the front, in the order shown on this listing, with the 'TOP' marking facing up.
- Wire each module: one-way uses COM and L1, two-way uses COM, L1 and L2, and an intermediate takes both pairs of strapper wires. For dimmers and 20A modules, follow BG's leaflet below.
- Connect the earth (green/yellow) cable to the earth terminal on the grid frame or metal plate.
- Screw the grid frame to the back box, then fit the front plate. Screwless plates clip over the frame.
- Switch the power back on and test every switch and dimmer.
