RE: FW: Electrical background
Regular relays do not hum. If it does this means it's switching on and off at certain frequency on which it's designed.

Re:RE: FW: Electrical background
Ross, You've got to define hum. A relay that is run off of an AC current can have a VERY faint hum. A relay that is running on AC current when designed for DC current has a distinctive 'hum' sometimes more similar to a high speed clicking. Also a relay that has a coil nearing the end of it's life will 'hum' as defined before. The best test I know of in this case is to observe the relay's contacts (possible only on open frame relays) in the dark. If there is a faint arc visible when the relay is suppose to be closed, it's time for a replacement. Dick Goulet BTW: Definition of 'VERY faint' is in a closed almost sound proof room with your ear right next to the relay.
