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

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.

| Terminals | Default | Action (Pressed) |
|---|---|---|
| C + NO | Device OFF | Device ON |
| 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. |
