FIELD: geophysics.
SUBSTANCE: invention relates to the field of geophysics. Switch is indicated that is actuated by a differential pressure, containing a mechanism that reacts to pressure, to provide a response to pressure in response to the pressure drop and an actuator of the device configured to interact with the mechanism, reacting to pressure, and for using the reaction to the pressure of the mechanism, reacting to pressure, to bring the device into operation. Actuator of the device drives the device into operation, when the pressure drop is below the lower differential pressure threshold, and can cause the device to be inoperative, when the pressure drop is above the upper differential pressure threshold.
EFFECT: technical result is an increase in the functionality of the device.
