Abstract: The invention relates to a field of electric equipment, in particular, to an electric light switch, namely, to a touch light switch to be mounted in a wall of a building. The set of essential features of the present solution enables to achieve such a technical effect as increase of convenience mainly increase of the light weight, the light switching on/off process due to provision of the large area of the touch area on the touch printed circuit board, thus, a high sensitivity on the touch display panel is achieved, i.e., along the entire front area of the device; simplification of mounting of the switch in buildings having old wiring and increase of safety of the device structure. This design of the touch light switch affects the correct operation of the device, thereby enhancing the receipt of signals and decreasing the probability of incorrect commutation of the switch and its failure during mounting.
