An electric leakage circuit breaker is provided to improve safety of a switch operation by installing a stopper member which limits a pressure of a test button on a unit case. An electric leakage circuit breaker includes a test button(8a), a returning spring(8b), a push switch(16), and a unit case(13). The test button which operates an electric leakage test switch is arranged to be opposite to an aperture of a case cover of a body by combining the test button and the returning spring. An electric leakage test circuit is configured by switching on the test switch with a manual pressure operation of the test button. The electric leakage test switch is mounted on a print plate. The push switch is received in the unit case. A button is protrusively formed on an upper part of the unit case. A flexible operation arm is extended from a button base to a side, and is opposite to an upper part of the operation unit of the push switch. The flexible operation arm is installed on the test button. |
