Looking for NE35Q3A Touch Tone dial pads for Northern Electric 2500 sets or equivalent.

This pad has 4 contacts: Red, Red/Green, White, Orange/Black.

I could use about 6 if someone has them kicking around or knows a source of supply.

Scientists say that the universe is made up of Protons, Neutron & Electrons. They forgot "Morons".
