Abstract

1448868 Electromagnetic relays PLESSEY CO Ltd 24 April 1974 20273/73 Heading H1N An electromagnetic relay has biased open movable tungsten contact surfaces 3, 4 formed as parts of respective magnetic core members 5, 6 having flanged ends 7, 8 to which resilient strip connections 9, 10 are attached and which are secured to an insulating base 11 such as a printed circuit board. The plunger type contacts are contained within the hollow interior of a coil 1 wound on a bobbin 2, and a curved screen 15 provides a return magnetic flux path as well as forming a housing for the coil and core members.
