surface mount black bakelite over-centre rotary intermediate switch

This collection of surface-mounted sockets and switches is a reproduction of historical models that have been brought up to current safety standards.
The 2.5 mm thick bakelite monoblock case guarantees you a superior quality product. Indeed, bakelite is a solid, lightweight, highly heat-resistant and electrically non-conductive material.
Please note that during assembly, the wiring and fixing from the inside is done directly on your wall. When mounting on a flammable support, be sure to close the back of the bakelite block with a mounting plate sold separately. It must then be drilled at the points indicated by the cutting line.

Do not use an electrical screwdriver
Do not use electrical screwdrivers when installing bakelite items. We recommend to first drill a hole in the wall, fit the right plugs inside and use a manual screwdriver to fix the screws in place. Be especially careful during the final tightening of the screws. 

Intermediate switches are used when three or more switches are needed to control one single light. For example, if four switches control the same light, you would need 2 two-way switches and 2 intermediate switches. This situation could arise in a staircase with several landings: a switch at the bottom of the stairs, a switch at the top of the stairs and a switch for each landing space.

Supplied without back cover. To be ordered separately.
