1. An electronic, contactless switching device, in particular with an ultrasound sensor having a basic unit accommodating the electronics and the securing means and a receiving part which can be joined to the said unit electrically by means of a connecting lead and mechanically in different positions by means of a supporting part, characterised in that the supporting part (8) is tubular and is clasped by a pipe clamp (10) and that between the ends (19, 20) of the clamp a supporting extension of the receiving part (11), formed as a flat part with a semi-circular end contour, is rotatably guided by means of a clamping screw (21) and held by it after it has been tightened, whereby the resilience of the clamp ends (19, 20) ensures that both the supporting extension (22) and the pipe clamp (10) are held in position on the supporting part (8). |
