Thats what I thought Robert..... I don't think I've seen anyone using the entire 4-1/2 inches..... with a little experimentation I think the 3 inches should work. At least you don't have to throw the thing away and start all over w/ a new button.

And Michael.... the rule gives a length dimension "base of (button) switch to top of plunger" it does not specifically state a length of travel. There is a difference.... for example.. the Harrington button has a pretty long (at least an inch or inch and a half) threaded portion for mounting. The plunger does not go past this portion of the button........ yet according to the current rule as written..... that threaded portion "might" be considered part of the length dimension from the "base of the (button) switch to the top of the plunger". Like a lot of rules.... it might require some clarifiction.... that is all I was referring to.
