Abstract (en)
An electric switch comprising at least one movable contact and one stationary contact, a movable mass, which in the distant position of the movable contact, when the switch is open, rests against the stationary contact opposite to the side which will stop the movable contact upon closing the switch, upon which the impact energy will be transmitted as pressure waves through said stationary contact towards said mass, which waves, upon reaching said mass will be converted into energy of movement of said mass, which is moved thereby away from the stationary contact to be held at a distant position from said stationary contact. Said mass can be driven away again from said distant position towards said stationary contact, such that upon striking this contact the impact energy will be transmitted as pressure waves towards the movable contact now, to drive this away from the stationary contact thereby opening the switch. This switch will be free from contact vibrations, will be opened with high velocity and needs little supplied operating energy.
