Abstract (en)

[origin: DE19712958C1] The invention relates to a switching device comprising a contact arrangement (3) with at least one displaceable switching element (14, 15) disposed on a rotational or displaceable contact arm (11), and at least one stationary switching element (8, 9). The inventive switching element (1) includes at least one first stop (16, 17) which limits the movement of the contact arm (11) when the contact arrangement (3) is opened. A movable braking body is used as a first stop (16, 17) to provide braking of the contact arm (11) without recoil even when high braking capacities are required once it reaches a predetermined end position. The material and the inertia of said braking body are adapted to the contact arm (11) in such a way that an impact occurs when the contact arm (11) hits the braking body (16, 17) resulting in significant braking of the contact arm (11) and displacement of the braking body (16, 17) in the direction of impact, for example. Further braking of the braking body (16, 17) can also be performed by a second stop (18, 19) or a spring, etc.
