Abstract

A switching device, in particular a circuit breaker, such as a line protection circuit breaker, at least one of whose switching contacts (2, 3) is connected, as a moving contact (3) via a kinematic system (4) which may be part of a latching mechanism (5), to a manual operating device (6), and whose contact erosion can be compensated for by means of an adjustable excess movement. It is provided, that, in the kinematic system (4), one element interacts as a clamping lever (9) with the moving contact (3), in that the clamping lever (9) or moving contact (3) has, in a stiff basic structure (33, cf. FIG 9), a web which can bend out as an adjusting web (10) which rests, by means of an engagement body (11), on an associated bearing edge (12) when the contacts (2, 3) are in the open position. <IMAGE>
