Abstract (en)
[origin: US5126710A] A high-sensitivity electromagnetic relay comprises a magnetic circuit polarized by a permanent magnet, a flux distributor, an operating coil, and a moving core cooperating with the flux distributor by means of an air-gap. A return spring passes completely through the core being inserted between the flux distributor and the external end of a guide tube, which is shaped as a bottle-neck having a widened part housing the core, and a narrow part capable of sliding in an aperture.
