I am looking for a couple of push button contacts from a Hercus machine from the 1970s-1980s. The buttons I am talking about where used on the Milling machine and the #1 Tool and Cutter grinder. The part I am after a couple of is Siemens 3SA10 Contact block 500V.
There are some on ebay but at over $100 for shipping I am holding of in case somebody who can ship to me more reasonably has something I can use.
This is what I got.
I'll send you a PM.
Ben.

sorry not the switches I am looking for. Here is a photo of the type I need. In particular the red one and the green one. the rotary knob for the light would be an absolute bonus too.

I am after the same as the original simply to make the machine look original so thanks for the thought Eskimo but at the moment I am holding out for the real deal. The machine has two VFDs buried inside but the only give away is the single phase plug. The Siemens mushroom head model 3SA11-40 is really all I need now. As BobL says i am only switching the 24v logic of the VFD's with the slight twist that I am switching it separately for each VFD to avoid connecting there separate logic circuits together.
I do have the stackable contacts that go behind the switch head on the way from the US so I am looking only for the actual switch actuator.
