K. INTERLOCK SYSTEM
(1) INTERLOCK MECHANISM
The door lock mechanism is a device which has been
specially designed to eliminate completely microwave
activity when the door is opened during cooking and thus
to prevent the danger resulting from the microwave
leakage.

SECONDARY SWITCHES TO THE LATCH BOARD
(3) INSTALLATION AND ADJUSTMENT OF THE LATCH
