This 22mm ultra-thin metal push button switch is a versatile, high-reliability solution designed for a wide range of electrical and industrial applications. Featuring a power symbol on the button face, it provides intuitive operation for users to quickly identify its function. The 4-pin terminal configuration supports seamless integration into complex circuits, while the momentary action (on-while-pressed) ensures precise, temporary control without latching. Engineered with a waterproof IP67 rating, this switch is fully protected against dust ingress and short-term water immersion, making it ideal for outdoor, marine, or high-moisture environments. Constructed from durable metal, it offers excellent corrosion resistance and mechanical stability. The ultra-thin design allows easy installation in compact devices, while its broad voltage compatibility (3V–220V) ensures flexibility for low-voltage electronics, automotive systems, or industrial machinery.
