More Information
Summary:A double pole double throw relay has two flexible electrically conductive contact arms which each carry an electrical contact positioned to engage cooperating contacts. Contact closing pressure is simultaneously applied to both contact arms by a yoke made of electrical insulating material which extends transversely of the arms and is pivotally connected midway of its length to an actuator which is positioned between the contact arms and is movable toward and away from the arms. The pivotal mounting of the yoke tends to equalize the contact closing pressure. In one embodiment, the yoke is supported by yielding means to provide a degree of overtravel which maintains pressure and compensates for contact erosion and water.
