Do precision
relays still have mercury-wetted contacts? Or have the RoHS
goons eliminated those too?
Mercury-wetted relays are obscenely expensive, but they are still around.
Can you stil lget the polarised-coil ones used on telegraph lines?
Really nice devices.
I always thoguth it was approrpatie when a local (to me, then)
elecctronics shop had a few suprlus such relays on sale. The name of the
shop was 'H. Gee'. Seriously.
