HTC4600 consists of a sensor and a main unit. The sensor detects touch through non-metallic/non-mirror surfaces with a thickness of up to 40 mm. When a touch is detected, the sensor sends a control voltage to the main unit, which is connected to the electrical installation on one side and to a load on the other. Upon receiving a signal from the sensor, the main unit activates a relay, which in turn switches the supply phase to the load. Therefore, this product can be considered a switch controlled by touching a sensor concealed behind a surface.
