With the rapid development of electric bikes and intelligent control technologies, the riding experience continues to improve. In this process, function buttons serve as the core interface between riders and vehicles, with increasingly diverse features such as brake lights, mode switching, horn activation, and lighting control. A key component enabling these functions is the “waterproof micro switch.”
Kangerle Electronics specializes in the research and manufacturing of micro switches. The launched KW1 series products, with their excellent performance and stable quality, have been widely applied in electric bike function buttons and multi-functional control systems, bringing great convenience and assurance to manufacturers and riders.
The Kangerle KW1 series waterproof micro switches currently include many models. It is structurally designed and performance-tuned specifically for electric bike application environments.
The main technical parameters of the product are as follows:
Rated Load: DC12V 0.1A
Circuit: SPST-NO/SPST-NC
Protection Grade: IP67 (after wiring)
Operating Temperature: -10°C ~ 60°C

These parameters ensure that the KW1 series switches maintain good conductivity and long-term stability in harsh environments, particularly meeting the high demands of the electric bike industry for reliability and weather resistance.
Application Scenarios in Electric Bikes
In modern electric bikes, waterproof micro switches are widely used for the following control functions:
- Brake Light Activation: Triggers the rear light when braking for safety alerts.
- Mode Switching: Switches between power modes or speed settings.
- Horn Control: One-touch activation for audible warnings.
- Lighting Functions: Controls headlights or turn signals.
- Accessory Controls: Manages additional features like anti-theft alarms.
The KW1 series switches features a compact design, ideal for embedding in limited spaces, especially suitable for electric bike handlebars with high integration and frequent operation.
Product Advantage Analysis
High Reliability
Electric bikes operate in various environments, demanding high temperature resistance and durability from components. The KW1 series has a wide operating temperature range of -10°C ~ 60°C, covering most regional climate conditions, ensuring stable operation even in extreme weather. Coupled with over 100,000 cycles of electrical life, it greatly extends the usage period and reduces after-sales maintenance risks.
Suitable Operating Force for Electric Bikes
The standard 120±30gf operating force is particularly suited for electric bike function buttons. This force effectively prevents accidental touches, improving operation accuracy, especially during riding where riders need quick tactile feedback to confirm actions. Kangerle’s force design provides clear, responsive feel, performing excellently in numerous manufacturer tests.
Compact Structure for Easy Integration
The KW1 series switches adopts a miniaturized module design, allowing flexible embedding into complex layouts of electric bike handlebars. It supports various shapes and materials for panel buttons, fitting current modular handlebar assemblies and transitioning to smarter systems.
Excellent Conductivity Performance
High-performance metal dome design and precision craftsmanship ensure reliable switch conductivity and anti-interference capability. Even under long-term frequent use or in environments with strong electromagnetic interference from electric bikes, it maintains stable electrical performance without jitter or skips, ensuring instant response in controls.
Practical Application Cases
Currently, Kangerle waterproof micro switches have been adopted by multiple domestic and international electric bike parts enterprises and vehicle manufacturers for batch integration in function button modules. In some models, the KW1 series switches is used for brake light control, with its stable operating force ideal for urban riding; it is also commonly applied in mode switching and horn buttons, where its size and response performance are well-compatible with mainstream handlebar modules.
Domestic Replacement Preferred: Kangerle Waterproof Micro Switch Benchmarking ALPS
In the wave of localization for electric bike electronic components, Kangerle Electronics not only meets the matching needs of domestic brands but also becomes the preferred replacement solution for many joint ventures and export parts enterprises. Represented by the KW1 series, the waterproof micro switches have successfully benchmarked and replaced ALP’s Waterproof Detector Switch SPVQ8 series models.
According to comparison data, Kangerle waterproof micro switches match ALPS in dimensions, installation structure, electrical performance, button feel, temperature range, and lifespan indicators, enabling seamless replacement without redesigning molds or circuit boards, helping customers quickly switch, reduce procurement costs, and enhance supply chain stability. Our KW1 series switches can fully replace ALPS’s Waterproof Detector Switch SPVQ8, but with advantages such as shorter lead times, lower prices, and customization availability.
Conclusion
With the development of intelligent controls and user interaction technologies in electric bikes, higher requirements are placed on buttons for intelligence, integration, and reliability. Kangerle Electronics, with years of deep expertise in micro switches, launches the KW1 series switches, which not only meets the stringent standards of the electric bike industry but also plays a key role in enhancing riding experience and operational convenience.
In the future, Kangerle will continue to refine product performance, expanding to more electric bike application scenarios such as throttles, display controls, and battery management, providing customers with more premium switch solutions to advance electric bike electronics toward smarter and safer directions.
Additionally, Kangerle offers localized technical support and fast delivery advantages, adapting to customers’ flexible needs from small-batch prototyping to large-volume supply. In terms of lead time control and after-sales service, it outperforms imported brands, further ensuring project implementation efficiency and stability.
