The shaft is moved when subjected to forces directed in pull and push directions, so that the unit delivers respective information in two positions. A ratchet (9) and a shoulder (10) are integrated to shaft and a washer (11) crosses the shaft to provide a hard spot during the movement of shaft from the equilibrium position to one of the two positions.</p> |
