Abstract (en)
[origin: EP0768687A1] The drive mechanism for a rotary signalling switch (1) links the rotary shaft (5) of the switch to the rotary shaft (6) of a contact actuator mechanism. The operation is such that the signalling contacts are open or closed when the switch contacts are open or closed. The drive shaft (6) turns at a speed (wht) whilst the signalling contact shaft turns at a higher speed (wcs). The linkage is provided by two discs (9,7) attached to the two shafts (5,6) respectively. The first disc has two radial slots (9A,9B) cut at intervals in order to receive two pegs (8A,8B) which are mounted on the second disc. Rotation of the disc (7) attached to the drive shaft thus also rotates the shaft (5) which supports the signalling contacts.
