Applications
This 16mm metal switch is widely used in Industrial control panels, CNC machines, Automation equipment, Electrical cabinets, Marine systems, and Medical devices. It serves as a reliable interface for any equipment requiring high-end tactile feedback and status indication.
Installation Guide
- Panel Drilling: Drill a 16mm (0.63") diameter hole on your control panel.
- Insertion: Insert the 16mm metal push button from the front side of the panel.
- Securing: Fasten the provided metal nut from the back to lock the switch in place.
- Wiring: Connect the 4 pins (Switch and LED) according to your desired circuit logic (Sync or Constant).
4-PIN LED Push Button Switch Wiring Guide
A 4-PIN switch consists of two parts: Switch Contacts (to control the device) and LED Terminals (marked with + and -). Below are two ways to wire the LED indicator.
- Horizontal Pins: The switch mechanism (Power In / Load Out).
- Vertical Pins (+ / -): The LED indicator light terminals.
Method 1: LED Synchronized with Device (On when Active)
Logic: The button light only turns ON when the device is running. It serves as a "Status Indicator."
- Wiring: Connect LED (+) to the Output side of the switch. LED (-) to Power Negative.
- Applications: Power start buttons, car fog lights, industrial machinery.
- Benefit: Saves power; provides visual feedback that the system is active.
Figure 1: LED turns ON only when button is pressed
Method 2: LED Always ON (Backlight Mode)
Logic: The button light stays ON constantly as long as there is power, regardless of the button position.
- Wiring: Connect LED (+) directly to the Power Positive. LED (-) to Power Negative.
- Applications: Dark environments, hallway switches, standby power indicators.
- Benefit: Allows you to find the switch easily in total darkness.

| Mode | LED Status (Idle) | LED Status (Pressed) |
|---|---|---|
| Sync (Status) | OFF | ON |
| Always ON (Backlight) | ON | ON |
Industry Knowledge
1. What is a 16mm Push Button Power Switch?
This is an electromechanical device used to control an electrical circuit. In industrial settings, the 16mm diameter is a standard size that balances space-saving on panels with ease of operation. The metal construction provides protection against environmental damage and vandalism.
2. Latching vs. Momentary Function
| Feature | Momentary (Self-reset) | Latching (Self-lock) |
|---|---|---|
| Action | Springs back after release | Stays in position (clicks) |
| Common Use | Horns, Doorbells, PC Power | Light switches, Power main |
LED Indicator Color Meanings
| Color | Standard Industrial Meaning |

Frequently Asked Questions
1. What is the difference between pin terminals and screw terminals?
Pin terminals (like on this model) are compact and support high-speed soldering or plug-in wire harnesses, while screw terminals are larger and suitable for manual wiring in electrical cabinets.
2. Can I use this 16mm switch outdoors?
Yes, it has an IP65 waterproof rating, meaning it is protected against dust and low-pressure water jets from any direction.
3. Is the LED resistor built-in?
Yes, FILN integrates the metal film resistor inside the switch, so you can connect it directly to your specified voltage (e.g., 12V or 220V).
4. How long is the mechanical life of this button?
It is tested for up to 500,000 mechanical operations and 100,000 electrical cycles.
5. Can I customize the LED to show two colors?
Absolutely. FILN supports bi-color (e.g., Red/Green) and tri-color customizations for status indicators.
6. What material is the best for medical devices?
304 Stainless Steel is recommended for medical applications due to its high corrosion resistance and ease of sterilization.
7. Does it come with the wiring harness?
This listing is for the switch only, but FILN provides custom wire harness services upon request.
8. What is 'Momentary' function?
It means the switch only stays ON while you are physically pressing the button. Once you release it, it resets to the OFF position.
9. Can it handle 220V AC?
Yes, this switch is rated for up to 250V AC with a 5A current load.
10. How do I choose the right hole size?
Ensure your panel has a precisely 16mm hole. Any larger and the switch may not secure properly; any smaller and it won't fit.
