VERFAHREN UND EINRICHTUNG ZUR BETAETIGUNG EINES ELEKTRISCHEN SCHALTERS ZUM EIN- ODER AUSSCHALTEN EINES BILDVERSTAERKERGERAETES, INSBESONDERE EINER BILDVERSTAERKERBRILLE

摘要

The ON/OFF switch for the image intensifying spectacle system is mounted on the head strap on the user's head. When the image intensifier is in position, mechanical tensile forces inside the head strap (13) etc., or between the device holder and the head strap (13) etc. are used to actuate the switch (1) for switching on. When the image intensifier is removed and the head strap is released, the switch automatically returns to its off position, thus ensuring that the image intensifiers are not left on when the spectacles are not in use.
