Well says it all. I have a little door phone and after about 6 months trying to keep the call/bell button has been abandoned in favour of an old bell push I found in a drawer with a Woolworths price tag on it. This is wired so it shorts the intercom cable as the original failed one which consisted of some tacky little push switch on a pcb glued in with heat glue. the Woolies on is your basic two brass bits sprung apart and a plastic button to short them together. Tis worked fine till one of two things happened. Firstly, its not waterproof and when its really wet, it shorts enough to make the bell sound or make silly whining noises leaving the amp running with clicks and groans. Or, the local cold caller or whoever who seems to have been studying finger karate, squishes it so much the prongs stay shorted out when the finger is removed. Most bell pushes seem to still be of this type. I had no idea of the stringent needs of a bell push in this environment before, so wondered if anyone else had any bright ideas? Brian
