7.7 Door lock with door microswitch incorporated
The door lock is an electromechanical device that powers electrical loads after the door has been closed
and the programme selector has been turned (ON/OFF closed).
It is fitted with a child safety device which, in case of need, allows the door to be opened by pushing from
the inside.
Door open:
the lever presses the button on
the switching device “A”; in this
position contacts 1-2 are closed.
In certain models, these feed the
drum lamp when the main switch
is closed.
When the door is closed:
the latch (1) turns the cam (2): this
movement releases the lever (3)
and the deviator button “A”
changes position, closing contacts
1-3 and thus powering up all
components in the appliance
(cutting the power supply to the
drum lamp, if there is one).
When the open door button is
pressed:
the main circuit board powers the
coil; the core (1), as it moves, acts
on the anchor (2), unlocking the
cam (3). The latter rotates and
moves the lever (4) which closes
the deviator contacts “A” in
position 1-2, and releases the
door latch (5).
