Abstract

359,275. Oil-break switches. MASCHINENFABRIK OERLIKON, Oerlikon, near Zurich, Switzerland. Dec. 4, 1930, No. 36611. Convention date, Dec. 21, 1929. [Class 38 (v).] The movable contacts of an oil switch are braked at the off position by means of a piston 3 on the cross piece 4 engaging a cylinder 2 located on the insulating member 1, which is slotted at 6, 7 to serve as a guide for the operating rod 5 and cross piece 4, respectively. The piston 3 may be grooved so as to allow oil to escape to a decreasing degree towards the final position.
