Product Applications

These switches are widely used in electrical equipment requiring circuit control. They serve as momentary reset button switches for:

• Industrial control panels
• CNC machines
• Automation equipment
• Electrical cabinets
• Marine systems
• Medical devices

Installation Guide

1. Drill a 19mm mounting hole in the control panel.
2. Insert the switch through the panel hole from the front.
3. Secure the switch by tightening the metal hex nut from the back of the panel.
4. Connect the wires to the 2-pin terminals using solder or connectors.

Wiring Logic: Normally Open (NO)

The FLM19-F-4-X functions as a 2-pin Normally Open (NO) switch. When the button is idle, the circuit is broken. When pressed, the circuit is completed.

Connection Mode	Default State	Action (Pressed)
Normally Open (NO)	Device OFF	Device ON

Industry Knowledge

1. What are 19mm Push Button Momentary Switches?

These are electrical switches designed to mount in a 19mm hole. The term "momentary" means they only remain in their active state while being physically pressed, returning to their default position once released. In industrial settings, they act as "triggers" for signals or power starts.

Frequently Asked Questions

Q1: Is this 19mm push button waterproof?
A: Yes, it is rated IP65 waterproof, making it a perfect waterproof 19mm momentary switch for outdoor and industrial use.

Q2: How many pins does the FLM19-F-4-X have?
A: This model is a 2-pin terminal push button, simplifying connection for standard momentary operations.

Q3: What is the difference between momentary and latching?
A: Momentary (Self-reset) means the button returns to its original position after you release it. Latching (Self-locking) stays in the pressed position until you press it again.

Q4: Can I use this in a car?
A: Yes, the 36V DC rating makes it ideal for 12V/24V automotive applications like horns or ignition triggers.

Q5: What material is the black version?
A: The black version is made of high-strength zinc-alloy black metal switch material with a corrosion-resistant coating.

Q6: Is it easy to install in tight spaces?
A: Absolutely. It features an ultra-thin metal push button design, specifically for small space installation switch needs.

Q7: Can I get this switch with a pre-wired harness?
A: Yes, FILN provides filn factory custom switch services, including wire length and connector assembly.

Q8: What do the different colors of buttons signify?
A: Red usually denotes stop/emergency; Green is for start; Blue/Yellow are for specific functions; White is a general-purpose indicator.

Q9: Does it support 220V?
A: The switch contacts support up to 250V AC at 5A, suitable for mains power control.

Q10: Are these switches certified?
A: Yes, they carry CE, VDE, RoHS, UL, and SGS certifications.
