ACTUATING SWITCHING DEVICE Russian patent published in 2019 - IPC H01H35/14 

FIELD: instrumentation; electrical engineering.

SUBSTANCE: invention relates to instrument making and electrical engineering, namely to an actuating switching device, and can be used in automatics systems of explosive dangerous technical facilities that can be exposed to emergency actions. Actuating switching device contains a housing, in which there is a threshold pressure difference sensor with membranes and a contact system with a pivotal cross-over switch switched by an electromagnetic drive. Electromagnet with external and internal coaxially placed magnetic circuits is installed on housing from contact system side. Disk with slots for the ledges made at the anchor of the electromagnet is set on the axis of the rotary cross-piece. Armature of the electromagnet is made in the form of a round plate of magnetically soft material pressed to the disc by a spring washer and having slots along the outer diameter, into which ledges are made on the end of the external magnetic conductor. External magnetic conductor is made as composite with the bushing enveloping it, conjugated with external outline of the anchor, which is made spherical with the sphere center on the longitudinal axis of the anchor.

EFFECT: high safety and reliability of operation of the device in wide fields of use, shorter actuation time are technical result.
