The 042 is the postwar manual version to the 022. Both are 31 inch radius I believe, but they are model numbers. The 022 has a reversible switching motor. The 042 manual lever can be used on an 022 or even an 042 radius switch etc. A manual switch cannot be used as an automatic one unless you really like to tinker but the 022 is a great deal used. In prewar the 021 is the manual o scale switch.

T-Man, he was asking about a manual 42" radius switch. The 042 is the manual version of the O gauge 022 switch, but it is 31" diameter. A 42" radius switch would be an O-84. I think he means a 42" diameter switch which would be O-42. With all this said, I don't know the answer if he is looking for a O-42 manual switch. I think Lionel lists O-27 height 42" diameter switches in their catalog, but I don't remember if they are manual or electric.

I am not sure either, that is why I am suggesting on switching the mechanism. It can be confusing.

That is my beef with e bay, all the track for sale and they seldom say the radius.

Bob Nelson at http://cs.trains.com/TRCCS/forums/95.aspx has some very detailed directions on how to convert O-27 switches to fixed voltage operation. If done inproperly, it can result in burned out switch motors. Some of the stuff he recommends is very clever.

Put "capacitive discharge" in the search engine. You will find a lot of threads. Bob explained to one of the guys how to wire the switches so he would have indicator lights on his control panel. Very clever.
