Trendiswitch Frequently Asked Questions

  • Do the screwless switches and sockets fit into standard back boxes?
Yes, the screwless switches and sockets are a dual plate system. The first plate screws in as normal, the second plate fits over the top of the first creating the screwless effect.
  • How deep must the back-box be in order to accommodate the switches and sockets?
The full Trendiswitch range will fit comfortably in a 25mm back-box. The minimum depth required is 16mm, however the bigger the air space around the module, the better the air flow will be around the module to promote cooling.
  • Are they supplied with screws & instructions?
Yes, the full Trendiswitch range is supplied with fixing screws & instructions on how to install the product. They are easy to install - simply replace your old switch as no additional wiring is required.
