Abstract

The compression spring holder is intended for the switch gear contact bridge support. The block, into which the compression spring ends penetrate may form the switching magnetic part of the electromagnetic switchgear. The part of the last turn of the compression spring may be formed by an actual connector of two such spiral springs. The part may be in the form of a multiple angled end of a helical compression spring. The parts of the last turn may be located in grooves of the housing section, to which the block is connected.
