  • Patent number: 5446326
    Abstract: A control circuit for a gearmotor is located internal to a plastic gearbox to reduce handling damage and damage resulting from exposure to the environment. The control circuit includes a metal track which provides an electrical conductive path for input power to an electric motor and electrical components and thereby eliminates the need for a printed circuit board. The metal track includes a plurality of alternative control circuits paths, the appropriate circuit being chosen during assembly of the gearmotor by selectively piercing knock-out tabs in the metal track. The metal track includes locking receptacles for receiving switch and d.c. motor electrical terminals and further includes crimping receptacles for receiving electrical component lead wires. The metal track is located on the internal surface of the plastic gearbox cover by integrally molded posts and is secured to the cover by ultrasonically or heat staking the posts.
