A contact spring (5) is tippably located on the same locating surface (3) as the rocking contact (4) which it activated, holding it in the 'on' position with the same force as in the 'off position. The spring is long, and is located in its central part. Its outer end parts (11,12) are each activated by adjustment heel formations (6,13) controlled by cam surfaces (7,14) formed on the rotatable breaker shaft (4). When the one other end part (11) of the contact spring in the rocking contact 'on' position is close to the breaker shaft (8), its other outer end part (12) is at a distance from that shaft. In the 'off' position of the rocking contact, the outer end parts are in opposite positions. The locating surface on which the rocking contact and contact spring are located is formed by the short end of the load switch 'on' and/or 'off' conductors (1,2). |
