Description

Technical Field

[0001] The utility model relates to the technical field of electronic switch buttons, in particular to a glue bonding structure combining a silicone button and a pot piece. Background Art

[0002] The application of switch components in the fields of automobiles and consumer electronics mainly focuses on the traditional silicone buttons / touch switches / micro switches. We will realize another switching method by combining ordinary silicone buttons with pot pieces:

[0003] 1. Traditional silicone buttons: The pressing stroke is high, and the conventional silicone button stroke range is 0.8-3.0mm.

[0004] 2. Touch switches: These are categorized into two types: pure touch switches, which lack travel and tactile feedback when pressed, making them prone to accidental touches. The other type utilizes touch, vibration, and pressure sensing. This approach requires more space for the switch button, is relatively expensive, and offers less than ideal vibration feedback.

[0005] 3. The micro switch (electronic button) needs to be mounted on the PCB. In order to solve the dust and water resistance of the assembly switch, another layer of silicone is needed to cover it. Therefore, a glue bonding structure combining the silicone button and the pot piece is needed to solve this problem. Utility Model Content
