- Yellow/Amber: Represents a warning or cautionary state that needs monitoring.
- White: Generally acts as a neutral power indicator or general status light.
Installation Guide (Threaded Mounting)
- Prepare the control panel by drilling a hole according to the 22mm dimension.
- Insert the metal push button switch through the hole from the top side of the panel.
- Place the rubber waterproof gasket and then use the provided metal nut to secure the switch from the back of the panel.
- Tighten the nut to ensure a firm, waterproof seal.
- Perform normal wiring to the 3-pin terminals (Common, NO, NC).
Wide Application Range
Any electrical equipment requires a switch to control the on/off state of the circuit. Our metal switches are extensively used in:
- Industrial Control Panels & CNC Machines
- Medical Equipment & Laboratory Systems
- Marine Control Boards & Outdoor Equipment
- Automation Lines & Robotics
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 |

Frequently Asked Questions (FAQ)
Q1: Is this 3-pin normally open switch available with an LED light?
The standard FLM22-HJ-1 is non-illuminated, but FILN can provide LED versions (Ring or Power symbol) upon request.
Q2: What is the mounting hole size for this 3-pin high-head switch?
This switch requires a standard 22mm (approximately 0.87 inches) diameter mounting hole.
Q3: How many pins does this non-illuminated metal switch have?
This model features a 3-pin terminal design, providing 1NO (Normally Open) and 1NC (Normally Closed) functionality.
Q4: Can I use this 22mm switch in a 12V DC system?
Yes, the contacts are rated for 5A and support voltages from low DC (12V/24V) up to 250V AC.
Q5: Does this 3-pin switch come with a pre-wired harness?
The base model is a pin terminal type, but we can provide pre-wired versions with custom cable lengths.
Q6: Is the high-head button more durable than the flat-head version?
Both have the same internal mechanism; the high-head design is simply preferred for easier activation while wearing gloves.
Q7: Is this 3-pin metal button switch waterproof?
Yes, it features an IP65 protection rating, making it suitable for damp and dusty industrial environments.
Q8: What is the difference between silver and black zinc-alloy shells?
Stainless steel offers better chemical resistance, while the black zinc alloy provides a professional aesthetic look.
