Abstract

244,851. Gath, J. H. Oct. 4, 1924. Addition to 175,794. Plug couplings, conabined with switches.-A plug D has a switch operating spindle E, provided with an actuating handle R at one end, and a key F at the other. The key passes through a flanged key-hole P in a small bracket L secured to a larger bracket K attached to the base A of the switch. Rotation of the spindle E causes the key F to engage behind the bracket L and prevent withdrawal of the plug and also causes rotation of the switch spindle G by engagement of the end thereof in a flat sided recess in the spindle E. Alternatively the bracket L is dispensed with, the key F then passing through the bracket K. Insulating washers U placed around the plugs, and if desired formed integral with the insulation V on the face of the plug D, are accommodated in recesses W in the cover C of the switch and thereby prevent exposure of the pins.
