Hello,
Can anyone tell me if there is a difference between a drum switch and a cam switch?

You are probably right, The advantage to the cam switch is it mounts flush on the machine, I guess that's the only upside I can think of. Why would these lathe companies go to the trouble and expense of using transformers and magnetic contactors when they could have mounted a drum switch of sorts mounted sideways connected to the apron switch. Can someone answer that? I have been wondering.My preference would be a drum switch. The innards are easily accessible if one needs
to refurb the contacts or braze on some silver to the contacts. The cam switch has too
many parts and not easily repaired for my way of thinking.
Thanks for the clarification, I knew there had to be a good reason, That's a lot of extra stuff.Contactor systems have several advantages over simple switches:
1) ability to incorporate a latching E-stop function- safer
2) greater current capability possible
3) ability to switch high power motors remotely with small switches
