Abstract
An electromagnetic beam switch for a laser resonator or generator, specifically for the guided or controlled transmission of light into a light conductor has two electrically controllable rotary magnets arranged in twin fashion for redundancy. Each rotary magnet operates a filter glass plate to tilt these plates into the beam path for interrupting the beam generation. The plates (13a, 13b) cooperate with respective switch contacts in corresponding switches (14, 15) arranged so that during activation, that is during switching-on, both rotary magnets (11, 12) are connected in parallel with each other. Upon completion of a "flight phase " or switch over phase the rotary magnets are automatically connected in series with each other to operate at half power as compared to the initial full power energizing phase. RC-components are arranged to prevent a constant activation of the magnets.
