Abstract

This plastic carrier is adapted to receive a pair of reed switches and a permanent magnet between the switches. Carrier 11, made of polytetrafluoroethylene or other resinous polymeric material, has apertures 13 and 13, each adapted to receive reed switches 15 and 15, in a longitudinal, friction-fitting manner. Aperture 17 holds permanent magnet 19 between reed switches 15 and 15', also in a friction-fitting manner. The external dimensions of carrier 11 are such that it can be slidably positioned in a bobbin having an electrical coil wound on it. When placed in such a bobbin, there results a normally closed, two-position reed relay. Carriers adapted to hold additional pairs of reed switches with permanent magnets between them can be used to realize normally closed, four- or six-position reed relays.

Reed Relay Module

This plastic carrier is adapted to receive a pair of reed switches and a permanent magnet between the switches. Carrier 11, made of polytetrafluoroethylene or other resinous polymeric material, has apertures 13 and 13, each adapted to receive reed switches 15 and 15, in a longitudinal, friction-fitting manner. Aperture 17 holds permanent magnet 19 between reed switches 15 and 15', also in a friction-fitting manner. The external dimensions of carrier 11 are such that it can be slidably positioned in a bobbin having an electrical coil wound on it. When placed in such a bobbin, there results a normally closed, two-position reed relay. Carriers adapted to hold additional pairs of reed switches with permanent magnets between them can be used to realize normally closed, four- or six-position reed relays. The friction-fitting relationship of the parts provides easy assembly, precise control of distances between the reed switches and associated magnets, and easy replacement of individual reed switches. By making the carrier of a polymeric material that is rigid enough to give the desired precise spacing, yet flexible enough to allow temporary movement of the reed switches when forces are applied to their contacts 21, damage or breakage of the reed switches is minimized.
