Abstract

1,009,728. Magnetic switches. H. DONATH. April 18, 1962 [April 18, 1961; Nov. 12, 1961], No. 14976/62. Heading H2B. [Also in Divisions B7 and G1] A magnetically operated train wheel detector comprises a pair of magnets 7, 12 and a sealed switch device including a pair of switch contacts 2, 3, made of a magnetic material, which are resiliently mounted on the web of a rail. The switch with open contacts may be positioned in the neutral zone 13 of the magnets such that when the zone is diverted by the presence of a train wheel 14 the contacts are acted upon by the magnetic field and close.
