INSTALLATION GUIDE

1. Prepare the panel by drilling a precise 25mm hole.
2. Insert the switch from the front side of the panel.
3. Fasten the metal hex nut from the rear to lock the switch.
4. Connect the pre-wired 4-pin leads to your power source and load.

TERMINAL TYPE COMPARISON

Terminal Type	Advantages	Best For
Pre-wired (4-Pin)	Quickest installation; no soldering; waterproof seal.	Mass production & outdoor use.
Pin Terminal (Plug-in)	Compact design; easy to replace using connectors.	PCB mounting or compact panels.
Screw Terminal	No tools needed except a screwdriver; high torque.	Field repairs & heavy vibrations.

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.

INDUSTRY KNOWLEDGE

What is an Illuminated Push Button Switch?

In industrial systems, an illuminated switch combines a manual actuator with an internal LED light. This dual-purpose design allows the operator to control the circuit while receiving visual confirmation of the machine's state (ON/OFF). The latching halo ring push button is specifically designed to remain in position after being pressed, whereas momentary resets instantly.

LED Color Meanings in Industry:

• Red: Stop, emergency, or fault detected.
• Green: System running, safe to operate.
• Yellow/Amber: Warning or process change.
• Blue: Special instruction or manual override.
• White: Neutral power indicator or general lighting.

FACTORY DIRECT SUPPLY

FILN Manufacturing Advantages:

• No Minimum Order Quantity (MOQ).
• Global Express Shipping.
• Full Customization (Wire length, Voltage, Connectors).

FREQUENTLY ASKED QUESTIONS

Q1: Is the 25mm 4-pin switch with LED suitable for 220V?
A: Yes, we provide internal resistance matching for 12V up to 220V AC/DC configurations.

Q2: Can I customize the wire length beyond 15cm?
A: Absolutely. FILN is a factory, and we can customize any wire length to fit your panel design.

Q3: What is the benefit of the power symbol illumination?
A: It provides a clear, universally recognized visual indicator that the device is receiving power.

Q4: What's the difference between Momentary and Latching?
A: Momentary resets when you let go; Latching stays pressed until you push it again.

Q5: Is this switch really IP65 waterproof?
