A device for connecting and disconnecting electrical or mechanical functions in a continuous sequence, comprising a cam shaft the cam means of which bring about said connection and disconnection, respectively, upon rotation of the cam shaft. The cam shaft supports a toothed disc cooperating with a toothed segment rotatably mounted on a second shaft, running in parallel with the cam shaft, on which second shaft is also supported a disc element cooperating with a wheel mounted on the cam shaft. Immediately upon rotation of the cam shaft, a tooth on the toothed segment will move the toothed disc for displacement of the cam shaft to operative position, wherein it switches on said functions. As soon as cam shaft rotation ceases, the toothed segment together with the disc element will bring the cam shaft back to its inoperative position of rest for disconnection of said functions. |
