Door Interlock - Electrolux TC2 Service Manual

7.8 Door interlock

The door interlock is an electromechanical device which powers the electrical loads only when the door is
correctly closed and the programme selector knob is turned (ON/OFF - closed).
The interlock features a child safety device so that, in case of necessity, the door can be opened by pressing
from inside the appliance.
Opened door:
the lever holds down the button
of deviator "A"; in this position
contacts 1-2 are closed. In some
models they power the drum
light when the main switch is off.
Position of connectors

Closing the door:
the latch (1) rotates cam (2): this
movement releases lever (3)
and the button on the deviator
"A" changes position, thus
closing contacts 1-3 and
powering all components of the
appliance (cutting power out to
the drum light)
