Abstract
An improved low cost relay which comprises a one-piece spool/base, a one-piece core/terminal and a one-piece yoke/armature (yokarm). A coil wound on the spool has one of its leads led to a wire which passes through the hollow stem of the spool for contact with the core upon its insertion into the stem. The stem also retains the yokarm in position with respect to the core and spool. A contact area on the yokarm moves against a contact area on a press-fit terminal mounted in the base with excellent wiping action. The other coil lead is led to a second wire mounted in the spool, and which is captured by a lanced split in a further terminal, which is also a press-fit in the base. A suppressor diode is received in the base and has one of its leads captured by the further terminal when inserted into the base, and its other lead received and captured between the yokarm and the base when the core/terminal is inserted. A backstop for the yokarm is provided by a cover for the device which is mounted on the base.
