#186447 - I would ground the Vee(gnd)
Responding to: Ashok Kumar's previous message
the button circuit (if you have shown it correctly, is an "any button" circuit.
clearly, if you want the indicators to work, you need to power it with 24V.

I would ground the Vee(gnd) of the micro circuit and use a resistive/OPamp "polarity converter" for both the A/D and the switches
