This Classic Simple Crossover Switch is the ideal solution to change giving a touch of design, the switches in your home. The product is called monoblock because it already includes the frame and can be installed directly into a universal flush mount box. Available in two colours, they are highly resistant and durable. Characteristics of the Classic Simple Crossover Switch The crossover switches are combined with the switches so that the same light can be controlled from as many switches as desired. They are widely used in double rooms where we want to be able to control the main light both from the door and from both sides of the bed. They are placed between two switched switches. These switches have the standard size, so they can replace any classic mechanism. In the accessories section you will find the frame for 2 and 3 modules. The connection of the cables is done by means of a quick connection, making the installation easier.
