Industrial Applications

A normally closed push button switch is vital for safety-critical circuits where the default state must be "connected." Common uses include:

• Emergency Stop Circuits
• Industrial Control Panels
• CNC Machine Safeguards
• Medical Equipment Fail-safes
• Marine Navigation Systems

Installation Steps

1. Cutout: Prepare a 16mm hole on your control panel.
2. Insertion: Insert the switch through the panel from the front side.
3. Securing: Use the included metal nut to tighten the switch from the back.
4. Wiring: Connect the 3-PIN terminals to your circuit as per the NC/NO guide.

3-PIN Push Button Switch Wiring Guide

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

What is a Normally Closed (NC) Switch?

A normally closed push button switch is a circuit component where the default electrical state is "connected." Pressing the button interrupts the flow of electricity. This is essential for safety applications like emergency stops, where pressing the button must immediately kill power to the system.

LED Color Reference (For Illuminated Versions)

• Red: Stop, Danger, or Emergency.
• Green: Go, Safe, or Normal Operation.
• Yellow: Warning or Standby.
• Blue: Information or Auxiliary function.
• White: Power Indicator or General Backlight.

Frequently Asked Questions

Q1: What is the main advantage of the high head actuator?
A: It provides a larger surface area and better tactile feedback, making it ideal for operators wearing gloves.

Q2: Is the normally closed push button switch waterproof?
A: Yes, it is rated IP65, meaning it is protected against dust and low-pressure water splashes.

Q3: Can I use this for a 12V DC system?
A: Absolutely. While rated up to 250V AC, it is perfectly suited for 12V and 24V DC industrial systems.

Q4: What is the difference between momentary and latching?
A: Momentary resets when you let go; Latching stays in the state until you press it again.

Q5: Does FILN provide custom wiring harnesses?
A: Yes, we offer pre-wired solutions and quick-connect sockets for all 16mm switches.

Q6: Is stainless steel better than aluminum?
A: Stainless steel offers better chemical and corrosion resistance, while aluminum is lightweight and available in black.

Q7: What does IK08 impact resistance mean?
A: It means the switch can withstand a 5-joule impact, making it "vandal-proof" in public or industrial spaces.

Q8: Can I get my company logo laser-etched on the button?
A: Yes, FILN factory provides custom laser engraving for logos and functional symbols.

Q9: What certifications do FILN switches carry?
A: Our switches are fully certified with CE, UL, RoHS, VDE, and REACH.

Q10: How long is the mechanical service life?
A: These switches are tested for over 500,000 mechanical operations.
