Abstract

The invention relates to a push type underwater switch comprising a base. A conduction assembly is arranged at the lower part of the base and includes a copper pin base provided with two copper pins;and springs are arranged at the lower parts of the copper pins. A triggering assembly is connected to the upper part of the base and includes an outer case; a moving sealing member is arranged at themiddle part of the outer case and is provided with an end cover; and a shaft hole is formed in the center of the outer case. A shaft of a key penetrates the shaft hole; a contact is arranged at the lower end of the shaft of the key; a copper ring is arranged at the lower end of the contact; and a compressed ring is arranged between the key and the end cover. A first sealing ring is arranged between the moving sealing member and the end cover; and a second sealing ring and a third sealing ring are arranged between the moving sealing member and the outer case. An inner cylinder is arranged at the lower part of the outer case; an outer cylinder is arranged at the upper part of the base and is in threaded connection with the inner cylinder; and a fourth sealing ring is arranged between the inner cylinder and the outer cylinder. The push type underwater switch with high sealing reliability has the pulse type triggering function; the heavy working current is allowed to flow through the switch. The push type underwater switch can be applied to underwater key type operating equipment.

Description

Technical field [0001] The invention belongs to the technical field of circuit switches, and in particular relates to a deep-water equipment switch, which is applied to underwater key-type operating equipment. Background technique [0002] In recent years, with the development of national defense and the continuous development of underwater resources, marine development and underwater defense of islands and reefs have been formulated by the state as the development focus. As a special combat force, the frogman unit is engaged in underwater safety protection and ordinary divers. There are more and more tasks to be carried out in resource development. They need to use various types of underwater equipment such as positioning, navigation, detection, and measurement when completing tasks underwater. These underwater equipment need a power switch to control the power switch of the equipment. Compared with general power switches, deep-water switches need to have better water tightness...
