Abstract
A position detector is used to detect the position of a piston in a cylinder, particularly when the piston is at one end of its stroke. The detector has a head (5) fitted to one end of the cylinder (8). It also has a plunger (2) with one end (22) protruding in the upper chamber (10) of the cylinder (8). The plunger (2) is displaced by the cylinder (1) when it is at the end of its stroke. The plunger (2) has a ramp (31) on which presses the moving rod (41) of a switch or valve (4). The plunger (2) is restrained by a coil spring (6) to return the plunger (2) to its original position once the cylinder (1) is removed from the plunger end (22).
