AI Technical Summary

Problems solved by technology

[0004] However, due to the increased number of parts and assembly steps, the tolerance stack-up between the button and its corresponding switch increases, which will impair the tactile feel of the button
The tactile feel of the button is also compromised when a waterproof element is placed between the button and the switch
Also, the extra friction caused by the waterproof element increases the risk of the buttons getting stuck

Embodiment Construction

[0039] figure 1 An embodiment comprising a switch 1 and a flexible assembly 14 is shown. The switch 1 is electrically connected to the flexible component 14 by, for example, reflow soldering. The flexible assembly 14 includes an L-shaped flexible piece 14a and a flexible reinforcing piece 14b that not only strengthens the flexible piece 14a but also guides the supporting plate 15 disposed behind the reinforcing piece 14b when the switch 1 is installed in an electronic device. The switch includes a switch main body 2 , a switch contact 3 , a switch contact cover 5 and a sealing member 6 .

[0040] The switch body 2 consists of plastic material and is preferably manufactured by insert molding. Furthermore, the switch body 2 is equipped with a stamped metal insert for use with signal wires welded to the flexible piece 14a. Such as figure 2 As shown, the switch body includes two sections, the first switch body section 2 a and the second switch body section 2 b, which are arra...

Abstract

A switch (1), comprising a switch body (2) having a first switch body section (2a) and a second switch body section (2b), a slot configured to be arranged on the first switch body section (2a) The switch contact (3) in (4), the switch contact cover (5) configured to cover the groove (4), and the sealing member configured to cover the outer periphery of the second switch body section (2b) ( 6).

Description

technical field [0001] The present disclosure relates to a switch having a sealing member and a push button structure including such a switch. Background technique [0002] Waterproof electronics are becoming more and more popular. The interior of such devices must be protected from water ingress to avoid damage to the device's electronic components. Adding a waterproof element to every hole or crevice in an electronic device makes the assembly more complex and takes up more space. [0003] The existing waterproof switchgear includes a button, a switch and an elastic sheet arranged between the button and the switch to protect the inside of the electronic equipment from water ingress. The elastic piece is provided with at least one hole so that the piece can be crimped onto the shaft portion of the button. This solution allows the waterproof element (ie the elastic sheet) to be arranged partly around the button, thereby reducing the space consumption and thickness of the s...
