Dual-actuation-mode control device

摘要

#CMT# #/CMT# The device has a fixed permanent magnet (10), and a microswitch e.g. micro-electro mechanical system, with a ferromagnetic membrane (20) driven between stable states. A mobile permanent magnet (11) is actuated between a position, in which the mobile and fixed magnets form a uniform permanent magnetic field to maintain the membrane in one of the states, and another position, in which the mobile magnet controls switchover of the membrane. A planar excitation coil (4) creates a temporary magnetic field to allow switchover of the membrane, when the mobile magnet is in former position. #CMT#USE : #/CMT# Electric circuit control device for use in a circuit breaker to automatically disconnect an electrical circuit in case of an electrical fault and to manually re-close the electrical circuit, and for eliminating leakage or standby currents in a system (all claimed) operating on a button cell or other battery. Can also be used for switching off a sensor such as wireless and standalone sensor, when data transmission is completed, and for eliminating leakage currents of transformers of alternating current/direct current power supplies that are utilized for powering or recharging roaming appliances e.g. mobile phone, digital walkman or camera. #CMT#ADVANTAGE : #/CMT# The control device is simple to use, easy to manufacture, reliable and compact. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of an electric circuit control device. 4 : Planar excitation oil 10 : Fixed permanent magnet 11 : Mobile permanent magnet 20 : Ferromagnetic membrane 21 : Mobile electric contact.
