Repairmen liked the clicking relays. They allowed the repairman to locate the correct card in an electrical closet that might have 100 or so in service. You asked the secretary to slowly operate the switch hook, until the correct one was found, by listening and feeling for the vibration. This was before the cards were equipped with LED's.
