Description

Technical Field

[0001] This utility model relates to the field of micro switch technology, specifically a micro switch button limiting structure. Background Technology

[0002] Microswitches, as a commonly used electronic component, are widely used in various electrical control systems, achieving rapid switching on and off of circuits through mechanical triggering. However, existing microswitches have some design shortcomings, especially in the control of the switch's travel distance.

[0003] Currently, most micro switches lack effective travel limiting structures, making it easy for users to damage internal components due to excessive pressure during operation. For example, excessive pressure on the switch button may cause the internal spring or contacts to deform or break, thus affecting the normal function and lifespan of the switch. Furthermore, since different application scenarios have different requirements for button pressing travel, the existing technology lacks a limiting structure that can flexibly adjust the travel, thus limiting the applicability of micro switches.

[0004] To address this, we propose a micro-switch button limiting structure. Utility Model Content

[0028] It should be noted that this utility model is a micro switch button limiting structure. The travel limiting rod 4 passes through the upper through groove 3 of the switch button 2 and is fixed to the upper outer surface of the micro switch 1. When the switch button 2 is pressed, the travel limiting rod 4 limits the travel of the switch button 2 in the through groove 3, thus preventing excessive pressing and damage to internal components.
