Abstract
A contact arrangement for switchgear with multiple disconnects by contact points connected in parallel of two contact bridges aligned in a contact actuation link uses a spring collar for a contact pressure spring. The spring collar has cutouts transverse to the spring-action direction into which the contact bridges with the spring collars can be inserted and locked in place transverse to their longitudinal direction. The spring collar is rounded at two facing sliding surfaces in the contact actuation link aligned transverse to the longitudinal direction of the contact bridges. This assures optimal fitting of the contact bridges to the fixed contact components without jamming the spring collar in the alignment.
