Key Features

• Elite Protection (IP67): Unlike standard IP40 buttons, this model provides complete dust protection and water immersion resistance, perfect for harsh outdoor or industrial environments.
• Ultra-Short Design: With a body length of only 26.5mm, it is designed specifically for control panels where depth is limited.
• Silver Alloy Contacts: Low contact resistance (<50mΩ) ensures high conductivity and reduces electrical arcing, extending the switch's lifespan.
• Momentary Function: The momentary push button resets immediately after being released, ideal for pulse-triggered operations.
• 4-Pin Simplicity: Two pins for the switch contact (1NO) and two pins for the LED (+/-), allowing for easy wiring and high-density installation.

Applications

FILN's lighted push button switches are essential components for any device requiring circuit control. Common applications include:

• Industrial Control: CNC machines, automation equipment, and electrical cabinets.
• Marine & Transportation: Marine dashboard systems and automotive fog light controls.
• Commercial & Medical: Medical diagnostic tools and dark-environment hallway switches.

Installation Guide

1. Drill a 22mm diameter hole on the mounting panel.
2. Insert the switch through the hole from the front side.
3. Tighten the metal hex nut from the back to secure the switch.
4. Connect the 4-pin terminals (2 for power/device, 2 for LED).

4 Pin Push Button Switch Wiring Diagram

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.

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.

Always ON (Backlight)	ON	ON

Industry Knowledge

1. What is a 4-Pin Lighted Push Button Switch?

It is a control component that integrates a switching mechanism and a status indicator. In industrial machinery, it serves as the human-machine interface (HMI) to trigger operations while providing visual confirmation via the LED ring.

2. Latching vs. Momentary: The Difference

Feature	Momentary (This Model)	Latching
Operation	Springs back when released	Stays depressed until pressed again
Typical Use	Doorbell, PC Power, Start Button	Light Switch, Main Power Toggle

Frequently Asked Questions (FAQ)

Q1: Is this 22mm push button switch waterproof?
A: Yes, it is rated IP67, meaning it is protected against dust and short periods of immersion in water. Q2: What do the different LED colors represent?
A: Red usually signifies "Stop/Danger," Green is "Start/Safe," Blue is "Special Function," Yellow is "Caution," and White is "General Status/Power." Q3: Can I get a custom voltage for the LED?
A: Absolutely. While 12V and 220V are standard, FILN can customize for any voltage from 3V to 380V. Q4: What is the benefit of the 4-pin design?
A: The 4-pin design separates the LED circuit from the switch circuit, allowing for more flexible wiring logic (e.g., LED on/off independent of switch state).
