Bakelite cross switch without frame for wall mounting.

Cross switches should only be selected when more than two switches are used for the same lamp and are installed between two staircase switches, for example in a staircase or in a basement when a light point is to be switched on and off from several locations.

If you want a regular switch to turn a light source on and off, or have two switches connected to the same lamp, you should choose staircase switches instead.
