Title:
AUXILIARY CONTACT BLOCK PROVIDING TEMPORARY CONTACT
Document Type and Number:
WIPO Patent Application WO2004044940
Kind Code:
A9
Abstract:
Disclosed is an auxiliary contact block comprising a housing (5) which encloses at least one fixed auxiliary contact (300) that is accessible from outside the housing and an auxiliary sliding member (100) that supports at least one movable auxiliary contact (310). Said movable auxiliary contact (310) can be brought in contact with the fixed auxiliary contact in order to modify the state of the auxiliary contact. The auxiliary contact block can be mounted onto an electric contactor in such a way that the auxiliary sliding member (100) is driven by the main sliding member of the contactor. The auxiliary sliding member (100) comprises two parts, one of which leads while the other one is led. One of said parts supports a pin (112) while the other part is provided with a groove that forms a closed loop and cooperates with the pin such that the led part (120) is moved in one direction (F1) so as to successively and temporarily close and open the auxiliary contact when the leading part (110) is displaced in a first direction (F) by means of the main sliding member, said one direction (F1) extending essentially perpendicular to the first direction. When the leading part is then displaced in a direction (O) running counter to the first direction (F), said leading part does not modify the state of the movable auxiliary contact.
