ABSTRACT:
A telephone line-switching device comprises first and second switches that interlock and a lock plate extending between the two switches. The push member of the first switch has a cam with which the lock plate usually engages. The push member of the second switch has an inclined portion on which the lock plate always bears. As the push member of the second switch is depressed, the inclined portion horizontally moves the lock plate, permitting the lock plate to disengage from the cam to release the first switch.
