    Jim I wouldn't bother with the 70Vdc has the 240Vdc transformer will power the 70Vdc and if you have bleed resistors on caps then they will be drained anyway, also the Drive LeD's will show any power left in the caps.!

    These are what I use on machine. . . Left to right.
    Control power ON/OFF 240Vac switch and Led light.
    Momentary Start/Reset button with 24Vdc Led
    OH SHITE BUTTON
    Limit over ride switch with 24Vdc Buzzer.

    Also on the Main box there's a master power contactor switch which controls main power to everything, VFD, vaccum etc.
