Permanent magnetic switch with two encapsulated armature contacts - has common flux circuit formed by armature contacts and stationary magnet

摘要

Each encapsulated armature contact consists of a magnetisable support plate with a perpendicular, magnetisable pin core at right angles to the plate plane and insulated from the same. Parallel to the support plate plane is a movably mounted armature. A magnetic field affecting setting element alternately short circuits the air gap of both armature contacts by displacement in the direction of the pin core long axis. - The two armature contacts form a common flux circuit, together with two flux carrying parts (16, 16'), a stationary magnet (17) bridging the armature contacts parallel to the pin cores (6, 6'), and the setting element (15). Preferably the flux carrying the parts are in the form of plates parallel to the support plate (3, 3'), their ends being bridged by the magnet, polarised in the long axis direction of the pin cores.
