Well, I was trying to drill the end out of it and had it "lightly" clamped in the vice. All of a sudden something went pop and the other end snapped off. I glued with Araldite but will have to wait till the morning to see if it will hold.
Since the old switches are looking very tired I was planning on spucing up with a new set. Haven't found much to choose from on eBay, it might be best to get another from the wreckers?
