ABSTRACT:
A contact finger module for mounting in a high-power switchgear includes at least one contact finger having a contact piece and a flexible contact piece support, which extends along a longitudinal direction and has an attachment end and a contact-making end. The contact piece overhangs the contact piece support in the opposite direction to a deflection direction, and is connected to the contact piece support at the contact-making end. The contact finger module includes at least one leaf spring, which extends along the longitudinal direction and has an attachment end at which it is connected to the attachment end of the contact piece support in the mounted state. The leaf spring can produce a force that counteracts deflection of the contact piece in the deflection direction. In the mounted state, the leaf spring can extend in the longitudinal direction at least as far as the center of the extension of the contact piece in the longitudinal direction.
