Abstract
A switch for a marine seismic sensor. The switch includes a bellows having a closed end, a side portion and an open end, wherein the side portion connects the closed end to the open end, the closed end includes a conductive surface, and the side portion acts as a spring; a base plug that includes first input and first output contacts on a first side and second input and second output contacts on an opposite side; and a plug located in the open end of the bellows and configured to form a chamber, inside which the second input contact and the second output contact are provided. The conductive surface short-circuits the second input contact and the second output contact when a pressure larger than a predetermined pressure (P) acts on the conductive surface.
