Abstract

582,536. Electromagnetic switches. OLDHAM & SON, Ltd., AKROYD, D. H. April 21, 1944, No. 7461. [Class 38 (v)] A r el a y which opens its contacts 10, 14 when energized is provided with means for adjusting the air gap when the armature 6 is in the attracted position and with independent means for adjusting the air gap when the contacts are closed. Thus the current at which it releases and the current at which it operates are independently set. In the form shown, the air gap for the attracted position is adjusted by rotating the screw 15 and the air gap for the release position is adjusted by rotating the nut 16 which bears on the spring 9 carrying the contact 10. In modifications two independent screws are used.
