Abstract

In an on-load tap-changer switch including moving and fixed arcing contacts (21 min , 22 min , and 14), the moving arcing contacts (21 min and 22 min ) are cylindrical rollers of such length as to cooperate with the fixed arcing contacts 14A, 14B etc. which are off-set in the direction of the longitudinal axis of the moving arcing contact rollers (21 min , 22 min ) so that erosion of the moving arcing contacts is spread along the length of each roller giving prolonged life or permitting softer materials to be used for the moving arcing contacts but not requiring more material to be used for the fixed arcing contacts 14. <IMAGE>
