ABSTRACT:
A direct current relay is disclosed, which is especially fit for railway type signalling systems. The said relay comprises a core (7) extending horizontally through a coil (8), an iron yoke (6) disposed above the core (7), and fixed to the core fore end, and extending along the coil (8) to the core rear end, an armature (11) pivotally mounted at the free end of yoke (6), in front of the corresponding rear end of core (7), and sets of moving and stationary contact members (C1, C2, C3, C4, C5) carried by moving and stationary, elastically flexible strips (24) which project in superposed and reciprocally spaced relationship from a contact carrier block fixed on the yoke (6). The free ends of the moving strips (24) are engaged with a vertically movable contact operator template (17) operatively connected with the armature (11) for movement of the moving strips, to cause the moving contact members (C1, C2) to be moved into or out of electrical contact with the stationary contact members (C3, C4, C5) when the relay is energized. The moving and stationary contact members are situated above the fore end of the yoke (6). Two counterweights (16) respectively arranged on either side of coil (8) are provided, which are operatively connected with the armature (11) for moving the same into rest position when the relay is de-energized.
