I had some of those years ago. I think it is used in the power supply of a TBY transceiver. I took one, added solder to the end of the reed to lower the frequency to 60 cycles, and used it to build a power inverter. At least you can clean the contacts easily. They are louder than an ordinary can vibrator, but nothing like the huge one in a PE-327 power supply used with a GRC-9.
