Abstract (en)
[origin: WO2012104377A1] The mobile part (35) of a vacuum pump comprises a circular spring (46) which slides on an external bearing surface (41) of the mobile part in most positions and which can enter a channel (40) as it relaxes in order to define an end position in which the vacuum bulb is open, thereby forming a lock. The mobile part (35) can be formed by two sections (38, 39) including one very electrically conductive, copper section which is directed towards the stationary contact (37) and which receives an element connecting to an external electric circuit. Section 38 can be made from steel in order to enhance the sliding of the spring without generating wear.
