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.
Claims20
A testable sealed relay comprising:
- a. a relay housing having a bottom wall with pins/terminals adapted to connect to a circuit, side walls, and an opposing top wall forming a cavity with electrical and contact components for carrying a current;
- b. direct, testable terminals located in said top wall directly corresponding to and in electrical communication with said bottom wall terminals;
- c. said testable terminals being formed as projections being one of flush with or extending from said top wall and being exposed to facilitate testing said relay by applying a multimeter device to test voltage.
A self-diagnosing 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 for carrying a current;
- b. a contact circuitry electrically connected to said components and at least two light-emitting diodes (LEDs), wherein one of said LED indicates primary signal that said relay is energized, and another LED light is a diagnostic LED and indicates if said relay is damaged;
- c. said top wall having apertures corresponding to each LED so that each LED is visible and adapted to be seen by a user.
A testable relay tool for testing a relay comprising:
- a. a top wall having a row of (+) Light Emitting Diodes (LED) and (−) LED indicators viewable from said top wall;
- b. each row of said (+) LED and (−) LED corresponds or aligns with terminals;
- c. a test button is provided that for feeding energy to one or more of said terminals;
- d. a (+) and (−) connection means for connection of said testable relay tool to a power source;
- e. a relay plug adapted to be plugged into a mating plug or a relay to test a relay.
