摘要

In the anti-bounce changeover switch contact assembly, the moving changeover assembly (2) moves on an axis (1) which is the centre point of the yoke (3) support for the fixed contacts. The fixed contact assemblies (4,4') are held on a retracting compression spring (8,8') assemblies and the side arms (3,3') of the yoke are similarly supported on compression springs (7,7'). Movement of the yoke and changeover contact unit is restricted by a striker assembly (5,5').PS.
