Two=way switching relay system - has static T=piece bearing two contacts towards which mobile contacts are resiliently biased

摘要

A two-way switching relay is used. The relay has a pair of resilient stalks on the top of which are the metallic contacts. These stalks are mobile into and out of the engaged position in a common actuating fokk (GF) which carries a slot to allow passage of the fork around a static talk. Stationary contacts are integrally mounted in a T-piece fixed atop the static so that by actuation of the fork moves the mobile stalks against the resilient bias of the mobile stalks towards the stationary contacts in the T-piece.
