The ocean exploration is not separated from the deepwater equipment and the underwater diving equipment, and the deepwater equipment is one of the key development directions of technological development. At present, underwater switches can be classified into shallow water switches and full sea depth switches from the point of view of rated use depth.
The shallow water switch always isolates the inner space and the outer space of the switch completely through the sealing ring, and the water pressure is resisted by means of elastic mechanisms such as springs or elastic sheets, for example, a tact press switch of a waterproof flashlight, the waterproof switch which is resisted by the springs is triggered when the water pressure is large and is not suitable for deep water, and if the elastic force of the springs is increased to resist the deeper water pressure, the switch is difficult to be pressed down in the air by manpower.
The full sea depth switch often adopts a rotary switch more due to the water pressure problem, for example, a magnet on a movable switch is moved, and the position of the magnet is judged through a Hall sensor so as to realize the switch function. Because the switch relies on the sensor to detect the magnetic field, the sensor must be powered on in real time with low power consumption to operate. A sliding/rotating waterproof switch form with magnets close to the reed switch is also useful, but the reed switch is typically a glass housing that is fragile and unusual in underwater equipment.
The full sea depth switch has a knob switch implemented by using the oil charge compensation of the inner and outer pressures, which requires filling the inside with hydraulic oil and making the pressure of the hydraulic oil of the inside approximately equal to the external water pressure to protect the housing and prevent leakage, and which has a complicated structure.
