Abstract
Testable sealed and/or self-diagnosing electromagnetic or solid-state relays simplify troubleshooting of electrical circuits. The testable relay comprises a relay housing with terminals adapted to connect to a circuit and an opposing top wall with testable terminals formed as projections being flush with or extending from the top wall and being exposed for testing the relay by applying a multimeter device. A self-diagnosing relay comprises a relay housing with terminals adapted to connect to a circuit, and at least two light-emitting diodes (LEDs). One of the LED indicates the relay is energized, and another LED light is a diagnostic LED and indicates if the relay is damaged.
Claims10
A self-diagnosing, testable sealed relay comprising:
- a. a relay housing having a bottom wall with pins/terminals adapted to connect a circuit, side walls, and an opposing top wall forming a cavity with electrical components including an electromagnetic coil for carrying a current;
- b. a contact circuitry electrically connected to said components and at least two light-emitting diodes (L.E.D.s), wherein one of said L.E.D. indicates a primary signal that said relay is energized, and another L.E.D. light is a diagnostic L.E.D. and indicates if said relay is damaged;
- c. said top wall having apertures corresponding to each L.E.D. so that each L.E.D. is visible and adapted to be seen by a user;
- d. direct, testable terminals located in said top wall directly corresponding to and in electrical communication with said bottom wall terminals;
- e. said testable terminals being formed as flat prongs flush on a horizontal plane with said top wall, so that said testable terminals are not protruded or indented, and being exposed to facilitate testing said relay by applying a multimeter device to test voltage.
