Abstract
A device for switching and elastically locking the end positions of movable switch parts, in particular switch tongues of grooved rail switches, including an axially displaceable rod (15) and a tube (17) surrounding the rod, in which a spring (29) encompassing the rod is braced against stops and locking members (26, 26′) capable of being displaced radially outwards are arranged, wherein the rod (15) has axially spaced-apart control stops (24, 25) for a radially inward position of the locking members (26, 26′) and the tube (17) has stops (32, 33) for the outward position of the locking members (26, 26′), wherein at least one (25) of the control stops (24, 25) of the rod (15) is displaceable relative to at least another one (24) of the control stops (24, 25) in the axial direction of the rod (15) and is capable of being fixed in the respective displaced position.
