  • Ground fault circuit interrupter with a unified test and reset switch mechanism
    Patent number: 4409574
    Abstract: The mechanism is operable by a single test/reset push button whose initial travel from a normal operating position causes closing of test circuit contacts while power contacts are engaged. Upon an actual or test trip actuating the trip solenoid of the interrupter, a latch member releases a member holding movable power contacts and also extends the push button out due to spring action to indicate the occurrence of the trip. For resetting, the same button is again pushed to reengage the power contacts in a closed position after which release of the button returns it to its normal operating position in which the mechanism is latched.
