ABSTRACT:
An electrical toggle switch assembly adapted for mounting from the rear of a bulkhead or support panel includes a bushing which pivotally supports an actuating lever and is inserted into a mounting hole in the panel. Secured on the outer peripheral surface of the bushing is a retainer made from an oriented fiber material including a plurality of short, relatively stiff, normally straight fibers which slant downwardly at an acute angle, preferably less than 45.degree., and normally extend outwardly from the bushing beyond the inner periphery of the panel mounting hole. As the bushing is pressed through the mounting hole, the fibers are deflected inwardly and a portion thereafter spring back to their normally extended position and grip the front of the panel in the area surrounding the mounting hole to hold the switch assembly on the panel.
