- Noise reduction: The spring absorbs part of the pressing impact, reducing the collision sound between the button and the shell for quieter operation. - Extended switch life: Spring cushioning lowers the direct impact on internal metal contacts, reduces wear, and prolongs the overall life of the switch. - Improved safety: In emergencies such as a blocked vacuum cleaner, the quick rebound enables one-key quick power-off to help prevent motor overheating. - Quick reset: The spring rebounds immediately after release to ensure the switch powers off promptly and to avoid continuous idling from accidental touch. Use scenarios: - Vacuum cleaners: helps stop the motor quickly if the intake is blocked, protecting the motor and improving safety. - Household appliances and tools: reduces noise and wear while providing reliable on/off control. - Devices with tactile buttons: minimizes risk of unintended idle operation from accidental presses through fast reset.
