<p>The adjacent switch housings (5, 6, 7) have each a movable contact bridge (8, 9, 10) each of which shunts a pair of contact fingers (11, 12, 13) in the closure position of the switch. Contact supports (15, 16, 17) are formed on a cross bar (14) of an actuation button (2) to support the contact bridges (8, 9, 10). Each housing (5, 6, 7) is provided with a return spring (25, 26, 27). The force of two springs only may bring the switch back to an opening position. In order to avoid a side jamming of the button (2), the latter is provided with two ribs (29, 30) which guide the button in a guiding path (4). </p> |
