Key Features

• Superior Protection (IP65 & IK08): Unlike standard IP40 buttons, this waterproof IP65 button switch is built for harsh outdoor and industrial environments, resisting dust, water, and impact.
• High Electrical Load (5A): While many 19mm buttons only support 2A, the FLM19 handles 5A 250V AC/DC, allowing direct control of higher power devices without intermediate relays.
• Premium Materials: Available in 304 stainless steel for extreme corrosion resistance, ideal for medical, food, and marine applications.
• Visual Clarity: Ring-illuminated power symbol with wide voltage support (3V-220V) ensures compatibility across global standards.
• Compact Short-Body Design: At only 26.5mm long, it fits perfectly in space-constrained panels like handheld devices and distribution boxes.

Industry Applications

This versatile industrial panel mount switch is essential for modern circuitry. Its latching metal push button function is perfect for power toggles, while the momentary power symbol switch serves as a reliable start/stop trigger. Common uses include CNC machines, automated assembly lines, marine dashboards, and high-end medical diagnostic equipment.

Installation Guide

1. Drill a 19mm diameter hole in the mounting panel.
2. Insert the button actuator from the front side of the panel.
3. Secure the switch from behind using the provided metal hex nut.
4. Complete the wiring according to your desired control logic (NO or NC).

5 Pin Push Button Switch Wiring Diagram

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

Industry Knowledge

What is an Illuminated Push Button Switch?

An illuminated push button switch integrates a light source (usually LED) within the button mechanism. It serves a dual purpose: acting as a manual actuator for circuit control and providing a visual "Pilot Light" to indicate system status (Power ON, Error, or Standby). In industrial settings, the ring-illuminated power switch is critical for safety and user experience in low-light environments.

Latching vs. Momentary: What’s the difference?

Feature	Latching (Self-Locking)	Momentary (Self-Reset)
Operation	Stay down when pressed; press again to release.	Springs back immediately after releasing.
Typical Use	Main Power, Light Switches	Doorbell, PC Power, Horn

Frequently Asked Questions (FAQ)

1. Can this 19mm switch be used with 110V or 220V AC?
Yes, FILN offers voltage customization from 3V to 220V AC/DC for the LED indicator.

2. What does the different LED colors represent?
Red: Stop/Danger, Green: Run/Safe, Blue: Reset/Special, Yellow: Caution, White: Power indicator.

3. Is the stainless steel version suitable for outdoor use?
Absolutely. The 304 stainless steel body combined with IP65 rating makes it perfect for weather-exposed panels.

4. How do I wire a 5-pin LED button for "Status Only" mode?
Connect the LED pins in parallel with your device load so it only lights up when the device receives power.

5. Can I get a custom symbol instead of the power symbol?
Yes, FILN provides laser-etching services for logos and custom industrial symbols.

6. What is the difference between Pin Terminals and Screw Terminals?
Pin terminals (like this model) are faster for mass production and allow for socket plug-in, whereas screw terminals are better for field maintenance without soldering.

7. Does it come with the rubber waterproof ring?
Yes, every switch includes a silicone O-ring for waterproof panel mounting.

8. Is there a warranty?
All FILN products come with a standard quality guarantee backed by our CE and UL certifications.

9. Can you provide the wire connector socket?
Yes, we sell a matching 5-pin quick-connect socket separately to simplify your wiring process.

10. How long is the mechanical life of the switch?
It is rated for 500,000 cycles, ensuring years of trouble-free operation in industrial environments.
