An initiator for a contactless switch comprises a support section (3) and an adjacent, conical-shaped control section (5), which has a sensor surface (11) and is free to move into several positions with respect to the front side of the support section. In one position, the sensor surface is turned away from the support section and in other positions it is parallel to the lateral surfaces of the support section. The control section is equipped with a prism-shaped recess in which is fitted a fastening element (4). The fastening element can be rotated about a longitudinal axis (6) that is perpendicular to the front side of the support section, and the control section can be rotated with respect to the fastening element about a central axis (7) which extends in the direction of a diagonal across the lateral face of the control section. A corner of the support section, which is adjacent to the fastening element, is bevelled in such a manner that, after the prism-shaped fastening element has been rotated through a predetermined angle about the longitudinal axis (6), the control section can likewise be rotated about the central axis (7) by an angle of 180 DEG and, after that, both the fastening element and the control section can together be rotated about the longitudinal axis (6). By this means it is possible to move the sensor surface of the control section into five different positions with respect to the support section.
