Electromagnetically controlled switching apparatus.

摘要

An electromagnetically operated switch, provided with a fixed magnetic core and a spring raised armature, which is locked against undesired switching-on by mechanical shocks, the locking consisting of two movable impact plates positioned according to the direction of switching and situated between the fixed magnetic core and the armature near the magnetic field of the switch. The impact plates are arranged on the armature so as to be rotatable in opposite directions in order to deviate into a cavity of the armature in the opposite directions when the switch is energized. Moreover, the impact plates can be maintained in the locking position under spring pressure.
