Abstract

An auxiliary contact arrangement for a switching device comprising a frame part (2), said auxiliary contact arrangement comprising: a first auxiliary contact position (5) arranged in the frame part (2), arranged to receive the auxiliary contact (8); and movable auxiliary contact control means (10) comprising a first control member arranged to control the auxiliary contact (8) mounted at the first auxiliary contact location (5) (11). The auxiliary contact configuration includes a second auxiliary contact position (6) disposed adjacent to the first auxiliary contact position (5), and the auxiliary contact control device (10) includes a second control member (12), the second control The piece is arranged to control the auxiliary contact (8) installed in the first auxiliary contact location (5) in a different manner from the first control piece (11) is arranged to control the auxiliary contact (8) installed in the second auxiliary contact location (5) 6) Auxiliary contacts (8).

Description

technical field [0001] The invention relates to auxiliary contact configurations for switching devices. Background technique [0002] A switching device is a device used to open and close an electric circuit. The switching means comprises at least one pole and control means arranged to open and close the pole. Switching devices include, for example, switches and switch fuses. Switching devices often include auxiliary contacts arranged to open and close circuits such as latches, alarms, and position indications. The auxiliary contact is adapted for a much lower current than said at least one of the switching devices. The auxiliary contacts are controlled by auxiliary contact control means which in turn are often controlled by the same control means as are used to control the poles of the switching means. [0003] The auxiliary contact configuration may comprise an auxiliary contact which is in its first switching position when the control means for the switching means is ...
