Abstract
A proximity switch including a base assembly rotatably carries a sensing head formed of a support part rotatable about one axis extending through a base assembly for positioning a sensing face on a complementary sensing part in any one of four planes parallel to the one axis. A pivot between for the support and sensing parts enable the sensing face to be placed in a plane transverse to the one axis by rotation about a second axis at 45.degree. to the one axis. Flexible connections extend along the one axis and stops between the sensing and support parts avoid undue twisting of the connections. An annular printed circuit board supported by the base assembly and a plurality of fine wires carried on an elastomeric member supported in the support part provides separable multiple connections between each conductor on the board and the flexible connections. A single fastening member retained by the base assembly and passing along the one axis through the board to either of a pair of diametrically opposed equally radially spaced fastening inserts in the sensing part permit the sensing head to be detachably secured to the base assembly in each plane and places the wires in pressure engagement with the conductors on the board.
