FIELD: physics.
SUBSTANCE: present invention relates to switch for marine seismic sensor. Switch includes a bellows having a closed end, a side portion and open end, in which the side portion connects the closed end to the open end, the closed end includes an electrically conductive surface and the side portion acts as a spring; a base plug that includes a first input and a first output terminal on the first side and a second input and a second output terminal on the opposite side; and a plug located at the open end of the bellows and configured to form a chamber within which a second input contact and a second output terminal are provided. Conductive surface closes the second input contact and the second output contact shortly when the pressure, greater than specified pressure (P), acts on electrically conductive surface.
EFFECT: technical result is to improve the information content of the received data.
