Abstract
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.
Claims5
A contact holder intended to move in a housing of an electro-magnetic contactor, the contact holder comprising two insulating parts which are joined together, the first part being connectable to a movable armature, and containing seatings intended to hold bridge contacts and their pressure springs, and the second part holding the bridge contacts in place by closing the seatings, characterised in that the first part is made of a material which will withstand arcing, and elongate openings are formed in the first part between the seatings intended to hold the contact elements, into which openings fit isolating partitions integral with the housing and in that these openings are blocked by the second part, which is formed from a plastics material having good antifrictional properties so as to serve as a guide.
