| 摘要 |
The moving contact piece (2) of the vacuum switch is connected to one end of a bellows (12) which is connected via an insulator (14) to the other contact piece (4). According to the invention, the insulator (14) is arranged on the other end of the bellows (12). In this embodiment, the annular-shaped insulator (14) has only a small diameter still and is largely protected against external mechanical influence. Furthermore, a vapour screen can be omitted since the normal bellows protection cap (20) also protects the insulator (14) against vapour effects. <IMAGE> |
