  • Patent number: 4010433
    Abstract: A flat type electromagnetic relay wherein respective members forming normally closed contacts and normally opened contacts and actuating such contacts are stacked on one another to substantially enclose electromagnet assembly of which core and coil frame are integrally formed to be flat. A balance spring urges a card operatively coupled to an armature of the assembly into non-attracted position of the armature for normal positions of the contacts with a balanced constant force with reference to attracting force to the armature and resilient force of normally opened contact spring. The assembly includes means for positioning the respective members when assembled with a single assembling direction.
