Reed Switch Overload Detector

This device incorporates a magnetic reed switch and a magnetic field arrangement which cooperate to provide an adjustable overload current detector.

Housing 1 of phenolic material contains channels 2 and 3. Channel 2, at its bottom, has four tapped holes symmetrically disposed to receive machine screws
4. Circular aperture 5 extends from the bottom of channel 2 through housing 1. Aperture 5 receives conductive loop 6, the extremities of which are connected to conductive support members 7 which, in turn, are receivable in channel 2. Conductive strips 8 are also receivable in channel 2. Screw apertures 9 of strips 8 register with apertures 10 in members 7. These apertures in turn register with the symmetrically disposed apertures at the bottom of channel 2. Screws 4 position and lock members 7 and strips 8 within channel 2. Channel 3 contains apertures 11 and 12. Apertures 11 are adapted to receive pluggable contacts 13 which are retained in apertures 11 by soldering to retainer plates 14. The latter are positioned and held in channel 3 by contacts 13 and extensions, not shown, which can be imbedded in housing 1. Screws 15 which are receivable in tapped holes 12 and 12a are utilized to connect external circuitry to housing 1.

Housing 1 contains cylindrical holes 16 and 17 drilled lengthwise of housing
1. Hole 16 is adapted to receive reed switch 18. TEFLON* washers 19 are placed on the leads 20 of reed switch 18 and are utilized to pos...
