Preparing 40-201 for painting chassis
#20

One thing I noticed in the action of the band switch - there does not seem to be a good positive detent to its action. It just slides through each position. There is a very slight feel of resistance as a band position is reached, but this just seems not right. I seem to remember seeing most band switches having a spring loaded ball bearing that provided a nice positive position feel. This band switch does not have any spring detent mechanism to it. There are two arms that are attached to the shaft and there are raised metal bumps on the front flange of the assembly but nothing is there to provide a positive detent. Is this normal, or has something broken and fallen out of the band switch?
