Abstract
A switch mountable in a feeding aperture in a support plate has an elongated housing having a base, a retention device for fixing the switch to the support plate, a switch plunger movable longitudinally against a spring action, a slider movable relative to the switch plunger and surrounding the switch plunger over a part of its length, radial vanes provided and guide grooves are guided in the guide grooves parallel to the longitudinal axis so as to move longitudinally up to opposite wall sections of the housing, limit stops for fixing the slider in an axial direction between the limit stops, notched tracks having locking teeth extending parallel to the longitudinal axis and provided on a shank of the plunger and inside the slider, which intermesh and fix the switch plunger to the slider in an axial direction when the switch plunger is turned with respect to the slider, the switch plunger with the housing being rotatable about the longitudinal axis with respect to the slider until a mutual engagement of the notched tracks takes place, and on further rotation the slider is released from engagement with the limit stops, and thus after adjustment of a length of the plunger, the slider …
