Retrofitting a 1986 Maho MH400E

The picture in the instruction manual just shows two switches in separate circuits. The text does list 24V nominal 10mA max 20 mA though. [strike]Doing a continuity test on all combinations of wires and button pushs gives no continuity, so it is not a passive device with two switches.[/strike] Doing the continuity test again with multimeter leads plugged in correctly reveals both switches are NC with white/green being the over travel switch and black/brown being the tool height switch.

PCW's recommendation was for a 2.4K pull up resistor. Now I am confused as it looks like mine is just two passive switches. Should I still use a pull up resistor? I have 2K2's here.

Making slow pregress on the pendant. Got the face done. Next step contour the side, round the edges, and then flip it over to hog out the back.

the pendand is the HARD WAY
you realy beat it up to the limit

I though of getting a cheap chinese pendant that would do 95% of what I want, but the 5% is wanting the tool release button on the pendant, so I decided to DIY.

Its not cheap but the Chinese remote pendant I use has 3 custom buttons on it that wire into I/O pins at the receiver end.

You can also and2 those 3 buttons to the yellow button so you could get another 3 functions.

But hey too late for you I think now!

You just have to select the right part number for compatibility...

That looks really nice. How reliable is the wireless connection?
