Switching contact assembly for an electrical switching element and electrical switching element

An electrical switching element, comprising:

• a switching contact assembly including a contact bridge having a pair of posts protruding from the contact bridge, a base, and a spring assembly, the contact bridge is attached to the base with the spring assembly between the contact bridge and the base, the contact bridge attached to the base is resilient in a direction opposite a switching direction, the spring assembly includes a pair of spring elements bearing directly against one another, a first spring element of the spring assembly is inserted into a second spring element of the spring assembly, the second spring element is a contact bridge retainer holding the contact bridge, the contact bridge retainer has a central region that is planar and a pair of contact bridge retaining legs extending from the central region in the switching direction, the contact bridge retaining legs are spaced apart from one another in a transverse direction of the contact bridge that is transverse to the switching direction, each of the posts is received in a lug of one of the contact bridge retaining legs, the contact bridge is movable with respect to the contact bridge retainer along the switching direction with the posts movable within the contact bridge retaining legs, the first spring element is a sheet metal that has a planar region parallel to the central region of the contact bridge retainer and abutting the central region of the contact bridge retainer, the first spring element has a pair of mounting points at opposite ends that extend in the switching direction, the first spring element bears against the contact bridge in a manner resilient in the direction opposite the switching direction only at the mounting points.
