-About the Switch
The switches provided in the printer are the push-switch detecting close/open of the door or cover
and the micro-switch for safety interlock to safeguard the user.
A push-switch closes the internal contacts via the plunger that is pushed down by the actuator of
the cover or door that is being closed.
When the door or cover has been opened, the plunger is pushed up by the spring in the switch
allowing the internal contacts to open.
A micro-switch closes the internal contacts via the button which is pushed down under the
provided leaf spring which is held down by the actuator of the cover or door that is being closed.
When the door or cover has been opened, the leaf spring returns to its original position and the
button is pushed up by the spring in the switch, allowing the internal contacts to open.
