What am I doing wrong?

This really has noting to do with the OP. I was just refreshing my
memory on latching relays and I found this:

Solved!!!

One of the new doorbell push-buttons was lighted; the previous two
were not. NONE of them worked! So I trashed them all and replaced
the original one with a simple brass doorbell button.

For all of us who contributed or lurked on this thread, it would have
been interesting if you had measured the resistance in ohms across the 2
terminals of the switches that did not work (both unpushed and pushed,
checking 2 cycles of push-release-push again-release again) versus the
one that does work and reported that here. If your trash has not been
collected, are you willing to retrieve at least one of the ones you
trashed, make the measurements, and let us know?
