Help with Electronics - Momentory Relay switching

[kerfworks]

1) Maxicam-M3 - you have an additional relay that is switched with the M3 (Spindle?) - so when you're cutting, the relay is on?

2) You have a separate Extraction system, that you want to use with the Maxicam?

3) The separate Extraction system has two momentary push buttons, for On and Off?

4) You want the relay on the Maxicam to effectively push "On" when the spindle is on? and push "Off" when the spindle is turned off?

Thanks JazzCNC, I should have explained it better. Doddy has understood it correctly - All of these are correct (I don’t think an M3 controls the relay but we have a different button on our control screen (Osai) that does and am sure can edit the post processor to get it to include the extractor switching.

These look exactly the units we need and not a bad price either. Thanks so much.

The extractor is a 10kw 3 phase motor and the wires going to the momentary switches are only very small and go to a contractor although not sure on the voltage. I will check.

We currently have a remote control on the extractor at the other side of the workshop and we are planning on wiring this up to act as another remote control but have a digital button not physical buttons.
