Abstract

The present invention provides a circuit interrupting device which comprises a novel reset mechanism to allow a user to test whether the device is wired properly. The novel reset mechanism includes a reset conducting apparatus which contains a reset start switch (KR-4). The KR-4 contains a first conducting pin, a second conducting pin, and a conducting bridge. When the reset button is depressed and the device is wired properly, the KR-4 is closed to allow the conducting bridge to be in contact with both the first and the second conducting pins so as to reset the device. The present invention also provides a circuit interrupting device which is capable of automatically checking the components of the circuit interrupting device (i.e., the end of life test) through a novel status test switch (KR-1). The KR-1 comprises a flexible metal piece and a simulated leakage current controlling resistor, which is located underneath of the flexible metal piece. When the circuit interrupting device is properly wired and at a tripped state, without touching any parts of the circuiting interrupting device, the KR-1 is closed which generates a simulated leakage current to allow the device to conduct the end of life test. If all of the components in the device are functioned properly, a reset indicating light is lit.
