Key Features

1. Superior Protection & Durability: Rated IP65 & IK08, this 16mm momentary push button switch is built for high-impact and wet environments. Compared to standard IP40 switches, FILN's metal buttons offer long-term reliability for outdoor equipment.

2. Optimized Electrical Load: Supports up to 5A 250V AC/DC. This high current capacity allows direct control of power devices without an intermediate relay, simplifying your circuit design.

3. Premium Material Selection: Options include 304 Stainless Steel for anti-corrosion and Silver Contacts (AgCdO12) for low contact resistance and anti-arcing performance.

4. Convenient LED Feedback: The ring illuminated push button switch provides clear status signals. Its pre-wired design with 15cm leads saves installation time for high-volume manufacturing.

5. Ultra-Compact Design: A total length of ~26.5mm makes it perfect for space-constrained control panels in handheld devices or dense electrical cabinets.

Applications

Essential for industrial control, this switch is widely used in CNC machines, medical devices, marine systems, and automation equipment. It provides a reliable interface for power starts and functional mode switching.

Installation Guide

1. Drill a 16mm hole in the mounting panel.
2. Insert the push-button switch through the hole from the front.
3. Tighten the metal hexagonal nut from the back to secure the switch.
4. Connect the 4-pin pre-wired harness to your power source and load.

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.
