On the machine our unit had, we did a lot of milling, and found that the contact points on the forward side got pitted- we switched them out with the points for the reverse side which were seldom used. We used the hi-low spindle brake on the lathe, so the switch was only used a few times per day. You could always change them out for a drum type switch, but that might be costly and require some knowledge of wiring. Otherwise just buy a couple new ones from shoptask and figure to get another 5 years use.
