Touch sensor for building installation technology

Abstract

A touch sensor 1 for building installation technology is disclosed, comprising at least one touch mat area TM1, TM2, TM3, TM4 of a touch mat module TM with at least one switching dome D1, D2 and with an actuating attachment element AE for mounting on the touch mat module TM, wherein the actuating attachment element AE has at least two light emission areas LA1, LA2, LA3, through which light from a light source L1, L2, L3 of the touch mat module TM passes to illuminate the light emission area LA1, LA2, LA3, wherein at least one of the touch mat areas TM1, TM2, TM3, TM4 has at least two switching domes D1, D2 and at least two light-emitting light sources L1, L2, L3 and the actuating attachment element AE has at least two light emission areas LA1, LA2, LA3 corresponding to the light sources L1, L2, L3.What is special about this is that for each light source L1, L2, L3 a light guide LL1, LL2, LL3 is connected to it, that shielding bridges A1, A2, A3 are arranged between the light guides LL1, LL2, LL3 on a shielding plate A for optical shielding of the light exit areas LA1, LA2, LA3, and that the shielding plate A is reversibly connected to the touch mat area TM1, TM2, TM3, TM4 by means of locking elements V.
