Sheltered homes for the elderly frequently have emergency "pull-cord"
alarm switches. I don't know whether these are "momentary" action or
"latching", but they are silent. I should imagine any wholesaler or
proper retail outlet would be able to source these "no problem".

They are 12V momentary usually, most definitely are if the ones you
have seen are silent.

The switches are usually rated 6A mains,

Probably some of the older ones are but most that I've fitted\seen
nowadays are 12V switches with a PCB inside with a surface mount PTM
switch on them, generally made by C-Tech, looking remarkably like this
lot, http://www.channelsafety.co.uk/T1I1P.asp?item=1503.
