Abstract
A miniature circuit breaker has an arc fault detector and a ground fault detector each with its own test circuit. Test switches for the two test circuits are mounted on a printed circuit board and share a common test contact formed by a flat U-shaped leaf spring. The common test contact is deflected into engagement with another test contact for one or the other of the two test switches by a remotely mounted common test button through a common test actuating member which is moved generally rectilinearly by rocking the common test button.
