Date 5.2.26 Description of Parts: RIGID CONTACT FIXED CONTACT POINT SUPPORT FOR CUTOUT Origin: Desirability of eliminating the flexibility of the present support which reduces the possibility of one sliding on the other. Experimental Test Report. Road Test Report. This item has run over 22,000 miles on chassis 8-EX in France and the condition of the contact points is very good. Sliding action is still taking place and the wear has been very slight with very little sign of burning. The arrgt. appears to be a definite improvement on the standard. Weight of Old Part.

ROYCE: 8.2.26, Agreed, but the sliding and flex was intended as a std. way of keeping switch contact points clean and making reliable contact, now you say better rigid: perhaps it is better. agree with less flexibility - let us be sure that what we are doing is better than increasing the area.
