发明名称 Contact-free switch for ball games
摘要 Preferably in game apparatuses and electronic billiards, inductive switches are switched according to the invention using balls etc. which do not consist of electrically conductive materials. A plurality of resonant circuits which pick up the amplitudes/frequency of the inductive switch as energy and switch the inductive switch are inserted in the billiard balls or other game elements. The technical values of the resonant circuit and the inductive switch must be matched.
