- Wiring: Connect the pre-wired 4-pin leads to your circuit according to the wiring diagram.
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 Waterproof Switch?
A 16mm push button waterproof switch is an electrical control component with a 16mm mounting diameter, featuring specialized sealing (IP65+) to protect internal contacts from moisture and dust. In industrial equipment, these switches act as the primary interface for users to safely start or stop circuits, even in wet or outdoor conditions. The metal housing adds an "anti-vandal" property, protecting against mechanical impact (IK08).
2. Difference Between Latching and Momentary
| Feature | Momentary (Self-Reset) | Latching (Self-Locking) |
|---|---|---|
| Action | Springs back when released | Stays in "pressed" position |
| Typical Use | Horn, Doorbell, Start pulse | Main Power, Light switch |
| Return Type | Auto-return | Press again to release |

A: Yes, it is IP65 rated, meaning it is protected against dust ingress and low-pressure water jets from any direction. The tail glue sealing further prevents moisture intrusion.
Q2: Can I customize the wire length for the FLM16-FW-1-E?
A: Absolutely. As a factory, FILN can customize the tail wire length and even add specific connectors to suit your project requirements.
Q3: What is the difference between stainless steel and black aluminum housings?
A: Stainless steel offers superior corrosion resistance for marine or food industries, while black aluminum provides a high-end, matte aesthetic for modern control panels.
Q4: Does the switch come with the necessary hardware for installation?
A: Yes, each switch includes a waterproof silicone O-ring and a metal hex nut for secure mounting.
Q5: Can I use this 16mm switch for 220V AC applications?
A: Yes, the switch contact is rated for up to 250V AC, and we provide LED options for 110V-220V AC.
Q6: What does "Momentary" mean for this switch?
A: It means the switch only stays active while your finger is pressing it. It returns to its original state once released.
Q7: Are samples available for testing?
A: Yes, we provide free samples for professional B2B customers. Please contact inquiry@cnylin.com.cn.
Q8: What is the benefit of the ring illuminated LED?
A: It provides clear status feedback and enhances the visual appeal of the equipment, especially in dark environments.
Q9: How do I wire the 4-pin pre-wired version?
A: Two wires are for the switch contact (circuit control) and two are for the LED power (+/-).
Q10: Does FILN have UL certification for these switches?
A: Yes, our button switches carry UL, CE, and RoHS certifications for global market access.
