摘要： PURPOSE:To get a stable switching operation having no erroneous operation in a hydraulic safety switch operated with a hydraulic pressure at a predetermined water depth by a method wherein when a safety pin is pulled up and hydraulic pressure entered at a hollow part of a housing is more than a predetermined pressure, a piston is slid to turn on the switch. CONSTITUTION:In a system in which an explosive having a hydraulic safety switch arranged therein is dropped to break a mine, sea water enters a hydraulic chamber 5 through holes 30, 31 when the mine is dropped into the sea. A safety pin 3 is connected to a wire of a running ship. As the safety pin 3 is removed from a projecting port 18 of a top cover 19, a housing 17 is pressurized by a compression coil spring 23. With such an arrangement as above, balls 21 are disengaged and a piston 6 is pushed downwardly by a pressure within a pressurizing chamber 5. As a hydraulic pressure within the pressurizing chamber 5 for pushing the piston 6 is higher than a sliding resistance force of an O-ring 27, a rod 8 drops through a through-pass hole 15 so as to cause a micro-switch 11 to be abutted against a main body 12 of the explosive.
