Understanding LED Colors in Switches

Although this model is non-illuminated, FILN provides custom LED options. Here is what colors represent in industrial standards:

• Red: Danger, Emergency, or Stop.
• Green: Ready, Start, or Safe Condition.
• Blue: Special Action, Reset, or Manual Override.
• Yellow: Warning or Abnormality.
• White: Neutral power status or General Illumination.

Key Features

1. Exceptional Protection: Rated IP65 and IK08, making it dust-tight, waterproof, and resistant to heavy impacts in harsh industrial settings.
2. High Load Capacity: Supports 5A 250V AC/DC, allowing direct control of power equipment without additional relays.
3. Premium Materials: Available in 304 Stainless Steel or Black Zinc Alloy. Silver contacts ensure low resistance and high conductivity.
4. Compact Design: A total length of approximately 26.5mm ensures the switch fits into tight control panels and handheld devices.
5. Versatile Mounting: Threaded installation with a metal nut ensures the switch stays secure in vibration-prone environments.

Applications

The versatility of the FLM19-FJ-1 series makes it suitable for diverse industries:

• Industrial Control Panels
• CNC Machinery
• Automation Equipment
• Electrical Cabinets
• Marine Systems
• Medical Devices
• Security Alarms
• Food Processing Equipment

Installation Guide

1. Drill a 19mm hole in the control panel.
2. Insert the switch from the front of the panel.
3. Slide the O-ring onto the switch body from behind.
4. Thread and tighten the metal nut against the panel to secure the switch.
5. Connect the wires to the 3-PIN terminals (Common, NO, or NC).

3 Pin Push Button Switch Wiring Diagram

A 3-PIN switch consists of a Common (C), Normally Open (NO), and Normally Closed (NC) terminal. Use these connections to control whether a device turns on or off when pressed.

• C (Common): Power input terminal.
• NO (Normally Open): Connects only when pressed.
• NC (Normally Closed): Disconnects when pressed.

Method 1: Normally Open (NO) Connection

Logic: Device stays OFF by default and turns ON only when pressed.

• Wiring: Power (+) to C, Device (+) to NO.
• Applications: Door bells, PC power buttons, car horns, momentary starters.

Method 2: Normally Closed (NC) Connection

Logic: Device stays ON by default and turns OFF only when pressed.

• Wiring: Power (+) to C, Device (+) to NC.
• Applications: Emergency stops, limit switches, fridge door light control.

C + NC	Device ON	Device OFF

Industry Knowledge

1. What is a 19mm Push Button Latching Switch?

In industrial automation, the 19mm push button latching switch acts as a physical interface for power management. A latching power switch 19mm maintains its state (staying depressed) once pushed, requiring a second push to release. This is crucial for equipment that needs to remain active without continuous manual pressure. The 19mm mounting diameter is an industry-standard size, ensuring compatibility with most commercial enclosures.

2. Latching vs. Momentary: Which do you need?

Function	Action	Typical Use
Latching	Pushes and locks in place. Push again to release.	Power buttons, Main Light switches.
Momentary	Springs back immediately after being pressed.	Door bells, Horns, Reset buttons.
