ifVheu -tlie movable part is open or released, the normal position of the plunger 35 is suoli, due to tlie action ot; the springs 3-9, that the conne-tion betweeii the contacts 40 eiidel ivillbebroken, and the seme action. of the springe swings tlie bell-crank levers 33 on their pivots inl the .arme 32, thereby moving the roller s nearer the movable port.
