Claim:
A relay comprising: a base; a pair of support members disposed on the base; two fixed contacts formed on the support members respectively; an iron core mounted on the base and formed in a U shape with two legs extending upward; two bobbins mounted about the two legs of the iron core; two coils wound on the respective bobbins; an armature formed in an inverted-U shape with a middle section and two legs extending down from the middle section through the respective bobbins toward the two legs of the iron core; a spring member joined to the armature; an insulator enclosing the middle section of the armature to isolate the armature from the spring member; two moving contacts formed on the spring member to be coupled with the fixed contacts; and a coil spring biased between the middle section of the armature and at least one of the two bobbins to normally urge the armature to an upper position where the fixed contacts and the moving contacts are spaced apart; wherein when electric power is supplied to the coils, the armature is actuated by the iron core to press against the coil spring, and the spring member moves downward with the armature to have the moving contacts in contact with the fixed contacts.
