Below is an LTSpice simulation of a 'radio button' circuilt. Ignore the bottom button, I am working on a 'reset' mechanism to unlatch any of the other buttons.

The idea is that the button you push, unlatches any other button and latches the button you pushed.

Does anyone know of a jellybean part (some 74 series type chip) that will do this?enter image description here
