Abstract

193,626. Frisby, W. Jan. 24, 1922. Electric switches.- A retarding-device for a switch comprises a tube A connected to the switch handle G by a cord F and containing oil and a metal ball B. The tube A is placed on an inclined shelf C with the ball B at the upper end, so that the ball gravitates slowly down the tube through the oil and eventually causes the tube to fall off the shelf C and actuate the switch.
