22mm Metal Push Button Switch

This 22mm metal push button switch stands as a robust, heavy-duty solution meticulously engineered for applications demanding foolproof power control and enhanced anti-misoperation safeguards. Its LED-free design simplifies functionality while minimizing potential failure points, making it an ideal choice for a wide range of industrial and commercial equipment.

Constructed from high-grade 304 stainless steel, the switch housing undergoes precision CNC machining and surface sandblasting, ensuring exceptional durability. This advanced manufacturing process not only fortifies the switch against oil, moisture, and chemical vapors but also endows it with superior wear resistance, capable of withstanding frequent use without scratching. The resulting non-slip, matte finish resists fingerprint smudges, maintaining a clean and professional appearance even in high-traffic operational environments.

With a 22mm hole diameter, this switch is designed to fit standard large-size control panel apertures seamlessly. It integrates effortlessly into industrial cabinets, heavy machinery consoles, and commercial electrical enclosures, eliminating the need for additional hole reaming or adapter parts. Installation is straightforward—simply embed and fasten, significantly reducing setup time. The button's stroke, optimized between 1.2-1.8mm, and a pressing force of 4-6N, provide distinct tactile feedback, indicated by a crisp "click" upon actuation. This calibrated design ensures reliable operation confirmation while preventing accidental triggering due to vibration or unintended contact.

Its core locking mechanism operates on a “press-to-lock, press-again-to-unlock” principle. Once engaged, the high-head button stays firmly in the “on/off” position, resisting accidental disengagement from equipment vibration or bumping—critical for main power control of production lines or emergency stop systems. The LED-free design streamlines wiring (no need for auxiliary power) and reduces failure points, making maintenance easier; to compensate for the lack of LED indicators, the high-head top can be optionally laser-engraved with power/logic logos (e.g., “ON/OFF”) that remain visible from a distance, leveraging the high head’s elevated position for quick identification on cluttered control panels

The switch's standout feature is its mechanical locking mechanism, which operates on a "press-to-lock, press-again-to-unlock" principle. Once engaged, the button remains in the "on" or "off" position until manually toggled, effectively preventing unauthorized operation or accidental activation caused by equipment vibration. This feature is crucial for critical applications such as production line main power control or emergency stop systems. The LED-free design further enhances the switch's practicality by eliminating the need for additional wiring and power supply, streamlining the circuit and reducing energy consumption. It is particularly well-suited for environments where light pollution is a concern, such as darkrooms or night-operating equipment, or where minimal maintenance is preferred due to fewer electronic components and reduced failure risks. For added functionality, an optional laser-engraved power logo on the button surface ensures long-term visibility, enabling quick identification of the switch's purpose without relying on LED backlighting.

In terms of electrical performance, this 22mm metal push button switch adheres to stringent industrial-grade standards. With a rated voltage of AC 250V/DC 30V, a rated current of up to 12A, an insulation resistance of ≥100MΩ, and a withstand voltage of ≥2500V AC, it offers reliable and safe operation. The switch also boasts an IP65 protection rating, providing dust-tight and water-resistant capabilities against low-pressure water jets.
