Recessed dimmer switch from Lineme, rotary, in silver color. It includes the mechanism and the faceplate of the switch, without a frame. It can be used in installations where we want to control the same device from 2 points, for example, the bedroom light, as it is aller retour. The power control is 400W. The number of watts helps us calculate the total power of the bulbs that we can control with a dimmer, the more watts, the greater the number of bulbs.
