Selective switching system for two circuits - has ON and OFF switch for each circuit coacting with cam on hand lever

摘要

The system is intended for trafficator purposes, particularly with electrically driven trucks. A pivoting lever can be arrested in both switching positions, as well as in its middle neutral position. For each circuit is provided an ON/OFF switch (12, 13) cooperating with a cam (3) coupled to the hand lever (16). The cam is associated with an elastically mounted arresting rail (9) via a special arresting element (5). The switches are of snap-action type actuated selectively by the cam in its respective switching position. Preferably the snap-action switches are miniaturised. The arresting element may be a roll, and the arresting rail may be pivotally mounted at one end, while supported by a spring (11) at the other.
