Description
|
The A400 Series 16mm Push Button Switch is designed for OEM control panels and compact equipment interfaces that require reliable switching performance, clear operation, and flexible appearance options. With a 16mm panel cutout and M16×1 threaded mounting structure, this series provides a practical solution for machinery panels, instrumentation, power equipment, automation systems, special vehicles, marine control panels, and other industrial control applications. This 16mm push button switch is available in illuminated and non-illuminated versions, with momentary or latching operation depending on the circuit requirement. The illuminated models can be supplied with different LED colors, button colors, and optional power symbol marking, making the switch easy to identify on control panels and suitable for start, stop, reset, power, signal, and function-control positions. For applications that require a clean panel layout, the LED push button version combines switching and visual indication in one compact component. The A400 16mm series supports different housing and wiring configurations, including metal housing versions, one-piece housing versions, solder lug terminals, and pre-wired waterproof lead versions. The standard electrical rating is 2A 250VAC / 4A 125VAC, making it suitable for signal control and low-current electrical control circuits. The switch is designed with IP67 protection, helping the front panel resist dust, moisture, splashing water, and demanding operating environments when properly installed. For long-term equipment use, the A400 Series 16mm push switch is built for stable mechanical operation, with a minimum electrical life of 50,000 cycles and a minimum mechanical life of 200,000 cycles. Custom options are available for LED voltage, button color, surface style, symbol marking, wire length, and terminal configuration, allowing equipment manufacturers to match the switch to their panel design, wiring method, and end-use environment. As a compact and customizable panel mount push button switch, the A400 Series 16mm is suitable for manufacturers looking for a reliable switch solution with multiple appearance, illumination, and wiring options for professional control systems. |
Applications
The A400 Series 16mm push button switch can be used in industrial control panels, machinery control boxes, power equipment, instrumentation, special vehicles, marine panels, automation equipment, and OEM control systems. The 16mm mounting size provides a larger operating surface than 12mm miniature push buttons, making it suitable for applications where clear operation, visible button colors, optional illumination, and reliable panel sealing are required. |

Q: What is the difference between the A4166 and A4167 versions?
A:A4166 is mainly used for solder lug versions, including metal housing and one-piece housing options. A4167 is the waterproof wire lead version, suitable for applications that require pre-wired installation and a better sealed wiring structure.
Q: What is the difference between A300 16mm and A400 16mm push button switches?
A: The main difference is the waterproof wire lead option. A300 16mm can be made with a metal housing and fully sealed wire leads. A400 16mm also has a metal housing option, but the metal housing version cannot be made as a fully waterproof wire lead type.
