My guess is that the relay coil current is around than 10ma. If it is around 10ma then the voltage would be 24VDC giving it a heat dissipation of .24 watts. This seems all very feasible to me and it may work with aslittle as 12 Volts.Are you looking for a replacement or are you just trying to get the specification to use the relay for some other purpose. If looking for a replacement and you can measure the resistance of the coil then I wonderwhat is wrong with the relay. Maybe the mechanism is damaged in some way?There were some latching relays that were used in remote control TVs a long time ago. They were a kind of rotary thing and every time the relay coil was energized the relay would go to the next position for a volume advance. There were generally 4 positions and the forth was POWER OFF. These were low voltage DC coils which ran from a 20 Volts or less source.
I wouldn't mind having a functioning version of one of those, to change taps on my bug-catcher.
Are there still any in existance, John? I wonder if Ken has any left, or did the flood(s) get all of that stuff? -- 73 = Best Regards, -Geoff/W5OMR
