| description | The present invention provides a switching apparatus having a design intended to reduce wear on its key part. In an embodiment of the invention, a rotatable member is rotatably fixed on a pivot. A slidable bearing member has a first surface for engaging the rotatable member in a non-sliding manner, and an opposite second surface for slidingly engaging an abutment. Any significant wear on the switching apparatus is more likely to occur between the sliding member and the abutment, rather than between the rotatable member and the sliding member. In an embodiment, one of the rotatable member and the slidable bearing member includes a protuberance, and the other of the rotatable member and the slidable bearing member includes a corresponding indentation for engagement with the protuberance. The join formed between the protuberance and indentation provides a substantially non-sliding engagement between the rotatable member and the slidable bearing member. |
