Abstract
A contact press-on assembly for a switching contact piece of an electrical switching unit has a first stop and a second stop. A spring element extends between the two stops, wherein the first stop can move relative to the second stop. The second stop provides a counterbearing for the first stop, wherein a rotary bearing for the spring element can move together with the first stop.
Claims11
A contact press-on assembly for a switching contact piece of an electrical switching unit, the contact press-on assembly comprising:
- stops including a first stop and a second stop, said first stop being movable relative to said second stop;
- and
- a spring element extending between said first stop and said second stop, said second stop forming an abutment for said first stop and at least one of said stops providing a rotary bearing for said spring element, said rotary bearing being movable together with said first stop, said rotary bearing protecting said spring element from transverse forces introduced from outside;
- wherein said abutment has a damping element for said first stop.

An electrical switching device, comprising:
- switching contact pieces including a first switching contact piece and a second switching contact piece, which are movable relatively in relation to one another;
- a kinematic chain serving for a relative movement of said switching contact pieces in relation to one another, said kinematic chain having a contact press-on assembly, said contact press-on assembly containing:
- stops including a first stop and a second stop, said first stop being movable relative to said second stop;
- and
- a spring element extending between said first stop and said second stop, said second stop forming an abutment for said first stop and at least one of said stops providing a rotary bearing for said spring element, said rotary bearing being movable together with said first stop, said rotary bearing protecting said spring element from transverse forces introduced from outside;
- wherein said abutment has a damping element for said first stop.
