EXECUTIVE SWITCHING DEVICE Russian patent published in 2017 - IPC H01H35/14 

FIELD: instrument making.

SUBSTANCE: actuating switching device comprises a housing which contains differential pressure threshold detector with the pressure receiving channel and coaxially mounted elastic membranes equipped with contacting elements, primary and secondary contact systems, an electromagnetic actuator with rotary armature. The differential pressure threshold detector is placed into a separate (isolated) housing consisting of a glass and plug forming a hermetic cavity between them, which has resilient membranes mounted on brackets, fixed in a glass and plug respectively. An electromagnet is installed in the glass in close proximity to the pressure receiving channel. The glass is externally equipped with cantilevered elastic plate of ferromagnetic material with the ability of the loose side to move before the pressure receiving channel due to the interaction with the electromagnet when power is supplied to the winding.

EFFECT: invention permits operation of the actuating switching device in case of the pressure change on set value relative to the pressure at a certain required time point.
