MAGNET-CONTROLLED CONTACT Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: magnet- controlled contact has sealed bottle, two contact cores produced from magnetically soft material placed on opposite butt ends of bottle. Longitudinal section of each contact core has S-shaped section put inside sealed bottle by zone of welding of contact cores with bottle. Contact is manufactured of magnetically soft material which value of coefficient of thermal expansion is chosen in compliance with difference of values of coefficients of thermal expansion of material of sealed bottle and of contact cores. EFFECT: facilitated manufacture, improved operational characteristics. 2 cl, 2 dwg
