An underwater device and its switching structure suitable for deep water

Abstract

This invention discloses an underwater device and its switch structure suitable for deep water. The switch structure includes a mounting shell, a push-button switch, and a resilient keycap. The mounting shell has a receiving groove and a slot, which are opposite to each other and have a telescopic channel between them. The bottom wall of the slot has a first support surface. The push-button switch is located in the receiving groove, and its telescopic post is telescopically inserted into the telescopic channel. When the push-button switch is not triggered, the telescopic post protrudes outward from the bottom wall of the slot. The resilient keycap is located in the slot, and its bottom has a first abutting surface that fits against the first support surface. There is a buffer gap between the resilient keycap and the top surface of the telescopic post. This switch structure can prevent the push-button switch from automatically triggering due to the high water pressure in deep water areas, facilitates user pressing of the resilient keycap to trigger the switch, and maintains the original tactile feel and "click" sound of the push-button switch, thus improving the user experience.
