I don't see where that gets us. The problem is in the switch body, not at the pushbutton/front panel interface. The pushbutton goes in and out just fine, and the rod. It's the latch in the switch that isn't working. It has to do with the little sprung rod thing and its small sprung cover. Now I look at it the FET switch isn't latching either. Never used it. But I see no difference from the other two switches that do latch perfectly.
