![CDATA[The ProxyTouch KNX is a capacitive touch sensor that can be installed discreetly behind surfaces such as ceramic, wood and glass. With its 3 sensor fields in a splash-proof plastic housing (size: 210x140x12 mm), it offers versatile operating options. The sensors can be activated individually, together or by swiping gestures, and each sensor also supports double clicks. For example, if you touch the tile behind which the device is mounted on one of the sensor fields (A, B or C), it sends a telegram to the bus. An acoustic feedback is optionally issued, with each key field assigned a different pitch (A=high, B=medium, C=low). In programming mode, a red LED shows the status and a buzzing tone is audible. In normal operation, an optional tone can signal the lock function of the button.]]>
