ELECTROMAGNETIC POLARIZED SWITCH Russian patent published in 2016 - IPC H01H51/00 

FIELD: blasting operations.

SUBSTANCE: invention is intended for use in automation systems of explosive objects. Electromagnetic polarized switch contains a case inside of which there are interacting magnetic and contact systems. Magnetic system consists of magnetic conductors with control windings, between which there is a clapper. Contact system consists of a contactor with ledges interacting with elastic contacts, arranged on the terminals arranged in the base of the case. Between the contact system and magnetic system two toothed sectors with ledges are installed. On the axis of the clapper there is a torsion spring with hook turn limiters. On the axis of contactor there is a gear wheel engaged with toothed sectors, interacting with one of its ledges when rotation of clapper with corresponding hook of a torsion spring. Initial moment provided by a torsion spring, exceeds the moment, required to turn the contactor when switching contacts.

EFFECT: technical result is increased resistance of the electromagnetic polarized switch to impact and vibration external effects and expansion of current ranges of switched electric circuits, which allows enlarging the application of the switch.
