Magnetic coupling for time piece - is designed to transmit instructions and has permanent magnet attached to rotating dial actuating reed switch contacts

摘要

The magnetic coupling for a time piece uses electrical or electronic circuits. The time piece is used for a transmission of time instructions. The time instructions can be used for example for functions in an automatic central heating system where the temp. is adjusted at different intervals. The coupling is intended for analogue time pieces, where a permanent magnet is attached to the rotating dial mechanism. The permanent magnet causes a contact to switch over to an alternative position. The permanent magnet can also be connected to one of the teeth of the rotating gears. The switching mechanism contains reed contacts and the position can be reversed with that of the permanent magnet.
