SENSITIVITY INCREASING METHOD OF MAGNETIC-CONTROLLED SWITCHES Russian patent published in 2017 - IPC H01H1/66 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric current commutators controlled by external magnetic field: magnetically controlled contacts (reed switches), microelectromechanical (MEMS) commutators and switches. The method is carried out by using a magnetic concentrator in form of isosceles trapezium, the upper (narrow) base of which is directed toward the contact overlap region. The angle between the lower base and the side of the trapezoid is 30-60°, and the ratio of the lengths of the upper and lower bases is in the range of 1:2-1:20.

EFFECT: increased sensitivity of magnetic-controlled switches without changing the parameters of their vibration resistance and resistance to impact caused by false closures under the influence of inertia forces.
