A complete radio transmitter switch allows for the control of home lighting using a remote control. Whether single or double, with or without a card, it is paired with a micromodule to avoid the need to pull wires during renovation work.

A complete radio transmitter switch consists of the following elements:

- a wire-free switch powered by a 3 V battery installed on the wall;

- a micromodule to be connected to the light fixture which can be hidden for more discretion;

- some models are equipped with a remote control.

Wire-free switches are distinguished by their characteristics:

- a simple model can control a single light fixture;

- a double model can control two light fixtures or two devices;

- the recessed models are placed in embedding boxes;

- the surface-mounted versions can be screwed to the wall or fixed using an adhesive.

The available models also differ by:

- their design;

- their color;

- their options (light indicators, card, etc.).

The following information helps in choosing the ideal radio transmitter switch:

- it allows to control not only light fixtures but also other devices such as roller shutters;

- in most cases, the kits include 2 switches and a module allowing the user to create a two-way circuit;

- some models are programmable to control the heating or the electrical circuit of certain household appliances such as the coffee maker or the television;

- models intended for outdoor use must have a protection rating of IP 55 or higher;

- a version with an IP 66 or 67 rating is preferable in case of risk of crushing.

Thus, the complete radio transmitter switch facilitates renovation work and allows for the control of devices using a remote control.
