Buffer In Between Switches for Logic circuits

danny davis said:

What kind of buffers or What analog logic chips can I use as buffer to put in between a Double or single throw switch to a Logic Circuit?

The Double Pole switch is going to switch from -10 volts to + 18 volts , but I need a buffer in between the switch to the logic circuit

Double pole switch ---> Buffer chip ----> Logic Circuit

My Manager said I need a buffer chip in between switches to logic circuit because from switching it can cause damage to the Logic circuit while switching, so the buffer chip protects it

Any reason why I need a buffer? for what reason? why not go direct without a buffer?

So a series resistor and zener diode would be best to be the buffer than?

The zener diode would Clamp the voltage to be safe
