Miniature dimmer/switch designed for embedding into ALU profiles with LED strips. Spring touch sensor rests underneath the diffuser of the ALU profile. The capacitive sensor is formed by a spring and a yellow LED which shines through the spring and transparent materials, such as the diffuser of the ALU profile for LED strips, visibly marking a circular touch point. If needed, the LED can be turned off. The maximum thickness of the material through which the sensor responds is approximately 3m
