40mm Metal Push Button Switch

The 40mm Metal Switch with Dot LED is a rugged, high-visibility electromechanical component designed for scenarios requiring clear status indication and reliable operation. With a 40mm installation hole diameter—larger than common 16mm/22mm models—it offers enhanced tactile feedback and easier operation, making it ideal for industrial, automotive, and outdoor equipment where visibility and durability are critical.

Structurally, its shell is crafted from 304 stainless steel or aluminum alloy, ensuring excellent corrosion resistance (resistant to salt spray, oil, and humidity) and impact resistance (withstanding up to 50N external force). It typically boasts an IP65/IP67 protection rating, effectively blocking dust and water splashes, suitable for workshops, marine environments, or outdoor control panels.

The integrated dot LED is a key highlight: available in red, green, blue, or amber, it provides clear "on/off" or "active/inactive" status signals (e.g., red for power-off, green for normal operation). The LED’s brightness (usually 50-100cd/m²) is optimized for both bright daylight and dim indoor settings, avoiding glare while ensuring visibility from 5-10 meters.

Functionally, it supports momentary (auto-rebound) or latching (maintained state) actuation. Electrical parameters include a rated current of 5-10A/250VAC, mechanical life of 500,000+ cycles, and operating temperature range of -40℃ to 85℃—meeting the demands of high-frequency use in industrial machines, emergency stop systems, or automotive dashboards.

Its large 40mm size also simplifies installation and maintenance, as it’s easier to align with panel cutouts and less prone to misoperation compared to smaller switches, making it a practical choice for heavy-duty control scenarios.
