Title:
冗長スイッチ
Document Type and Number:
Japanese Patent JP4834062
Kind Code:
B2
Abstract:
A redundant switch includes a housing and an actuator movable in the housing in two opposing translational directions. A slide (16) is movable in the housing in the same two opposing directions as the actuator and is coupled to the actuator by two antagonistic springs (28a,28b) with clearance in both directions of movement. The switch also includes a latching track (18) with at least two latching notches, which are spaced from each other along the directions of movement. At least two switch units (26a,26b) are arranged one beside the other for simultaneous actuation by the slide. A latching cam (22) is movably guided on the slide perpendicular to its directions of translational movement and is urged towards the latching track by a compression spring. One of the latching notches in cooperation with the latching cam defines a rest position of the slide, in which the slide does not actuate the switch units. Another latching notch in cooperation with the latching cam defines an actuating position of the slide, in which the slide has actuated the switch units. The antagonistic springs (28a,28b) force the slide to move into the respective other position, when the latching cam slides over an apex between the latching notches.
