Arrangement for change-over contact apparatus protection with

The invention relates to a contact holder for an electromagnetic contactor or relay, the contact holder being slidably displaceable within a contactor housing by the contactor armature to guide the armature and change the contact state between movable contacts carried by the contact holder and fixed contacts carried by the housing. The contact holder comprises first and second parts formed from insulating material which are joined together, the first part being connected to the armature and provided with seatings on which movable bridge contacts are located, and are held in place by the second part. Elongate openings are formed in the first part between adjustment seatings, and isolating or anti-arcing partitions integral with the housing extend through the openings.
