    摘要: A miniature transfer relay has a base mounting a contact assembly and an electromagnet. The contact assembly includes a normally-open (NO) fixed contact, a normally-closed (NC) fixed contact, a common conductor, and a movable spring extending from the common conductor and carrying first and second movable contacts engageable respectively with the NO and NC contacts. The electromagnet block includes an armature which is movable between set and reset positions and is connected to the movable spring for making and breaking the NO and NC contacts simultaneously in response to the armature movement. The NO fixed contact and the common conductor are molded in an upper surface of the base, while the NC fixed contacts has a portion molded in the base. The movable spring is an elongated self-biased resilient member which is formed at one longitudinal end thereof with the first movable contact and which is secured at the other longitudinal end to the common conductor such that the movable spring can resiliently flex in a cantilever fashion to move the first movable contact into and out of contact with the NO fixed contact. The relay is characterized in that the movable spring carries the second movable contact at a portion intermediate its longitudinal ends and on a surface opposite of the first movable contact, and that the NC fixed contact extends upwardly from the base and is bent over the movable spring to be kept in normally closed relation to the second movable contact.
