ABSTRACT:
A switching mechanism in a star-delta-switch with a rotatable and axially displaceable switch-shaft prevents rotation of the switch-shaft from the off- to the delta-connection position in the direction of rotation from the delta-connection to the off-position in one of the axial positions while axial displacement of the switch-shaft to another axial position enables the switch-shaft to be rotated from the off- to the delta-connection, rotation of the switch-shaft in the other axial position causing the switching mechanism to reset to the one axial position.
