ABSTRACT:
A cover for a leaf switch comprises a cover body having defining a space which receives contact elements of the leaf switch. The cover body engages with a movable contact element to allow the leaf switch to be actuated as a result of movement of the cover body and receives a fixed contact element. The fixed contact element is kept still when the movable contact element is moved together with the cover body. The arrangement described had been found to be effective in preventing or reducing contamination of the contact elements of the leaf switch by dust.
