I cannot give you a electricians answer Bill but I can tell you that
maybe find someone who lives and or works in someplace like Louisville
where they do have the talking signal button and one that tells you
what intersection you are at. I wish I could remember the mans name
but he was walking from work in Louisville with his guide dog and I
could hear the street/ intersections being announced and he said" no
that is not mine" and they continued. then when it said something like "
baker and stone". well at that intersection I believe the man pushed
the pole button as you said you wanted to do Bill. I got that off from
blind cool tech some time ago. Lee
