Applications

This 16mm metal button switch is indispensable for Industrial control panels, CNC machines, Marine systems, Medical equipment, and Electrical distribution cabinets. It serves both as a primary power control and a functional trigger for complex circuitry.

Installation Guide

1. Drill Hole: Create a precise 16mm hole in your panel.
2. Mount Switch: Insert the switch from the front of the panel.
3. Secure: Tighten the metal hex nut from the back to lock it in place.
4. Wire: Connect the 5 pins according to your desired circuit logic (C, NO, NC, LED).

5-PIN LED Push Button Switch Wiring Guide

A 5-PIN switch offers maximum flexibility, featuring C (Common), NO (Normally Open), NC (Normally Closed), and two dedicated LED pins (+ / -). This allows for four distinct control modes.

1. Normal OFF, Sync LED (NO Connection)

Logic: Both the device and the LED are OFF by default. Pressing the button turns ON the device and the LED simultaneously.

• Application: Standard start switches where the light indicates the system is running.
• State: Static (LED Out, Device Off) → Pressed (LED On, Device On).

2. Normal ON, Sync LED (NC Connection)

Logic: Both the device and the LED are ON by default. Pressing the button turns OFF both the device and the LED.

• Application: Stop buttons or emergency cut-off switches.
• State: Static (LED On, Device On) → Pressed (LED Out, Device Stop).

3. Normal OFF, Constant LED (NO Connection)

Logic: The LED stays ON constantly as a backlight. The device only turns ON when the button is pressed.

• Application: Power switches in dark environments or access control buttons.
• State: Static (LED On, Device Off) → Pressed (LED On, Device On).

4. Normal ON, Constant LED (NC Connection)

Logic: The LED stays ON constantly. The device is ON by default and turns OFF when the button is pressed.

• Application: Monitoring systems or security alarms that require constant power indication.
• State: Static (LED On, Device On) → Pressed (LED On, Device Stop).

Mode	LED Behavior	Device (Idle)
NO Sync	Lights up when pressed	OFF
NC Sync	Turns off when pressed	ON
Constant	Always ON (Backlight)	User Choice

Frequently Asked Questions

1. Can this switch handle 12V DC systems?
Yes, it is perfectly rated for 12V DC, making it a popular choice for automotive and marine electronics.

2. What is the benefit of the 'High-Head' design?
The high head provides a larger surface area and deeper travel distance, ensuring a more positive 'click' feel, even when wearing gloves.

3. Is the LED resistor built-in?
Yes, all FILN illuminated buttons come with internal resistors matched to your specific voltage requirement (e.g., 12V or 220V).

4. What does 'Momentary' mean?
A momentary switch returns to its original state once released. It only remains 'Active' while the button is being held down.

5. Can I use the LED as a backlight only?
Yes, by wiring the LED pins (+/-) directly to the power source, the ring light will stay on regardless of the switch state[cite: 9].

6. Is it truly waterproof?
With an IP65 rating, it is protected against low-pressure water jets and is suitable for outdoor or wash-down environments.

7. Do you offer black metal options?
Yes, we provide both 304 stainless steel (silver) and anodized aluminum (black) versions of the 16mm button.

8. What are the 5 pins used for?
The 5 pins include the Common, Normally Open, Normally Closed terminals, and two terminals for the LED[cite: 1].

9. How long is the electrical lifespan?
It is rated for over 100,000 electrical cycles and 500,000 mechanical cycles under standard operating conditions.

10. Does FILN provide wiring harnesses?
Yes, as a factory, we can customize wire lengths and attach specific connectors for your assembly line.
