120V Push Button Switch Stainless Steel Momentary 4-Pin Screw Terminal LED Switch | FILN

The 120v push button switch (Model: FLM19-FS-1-E) is a high-performance 19mm-momentary-push-button-switch designed for demanding industrial environments. Manufactured by FILN, this stainless-steel-push-button features a brilliant ring LED and a robust 4-pin-screw-terminal-switch design for secure connections. Certified with ISO9001, CE, VDE, RoHS, SGS, UL, and IP65, it ensures maximum safety and reliability. This momentary-metal-button-switch is widely used in industrial-control-push-button systems, CNC machinery, and medical devices, providing a sleek ring-illuminated-push-button aesthetic with superior tactile feedback. Whether you need a 120v-led-push-button-switch for power control or a waterproof-industrial-button-switch for outdoor equipment, FILN provides professional customization to meet your specific needs.

1. Superior Protection (IP65 & IK08): Unlike common plastic switches, our 19mm-panel-mount-switch offers IP65 waterproof and IK08 impact resistance, ideal for harsh industrial environments.
2. High Electrical Load (5A): Supports 5A 250V AC/DC, allowing direct control of high-power equipment without extra relays.
3. Screw Terminal Convenience: The 4-pin screw terminal design provides a stronger physical connection than soldering, making it easier to install and maintain in high-vibration machinery.
4. Premium Materials: Constructed with 304 Stainless Steel for anti-corrosion and Silver Alloy contacts for low resistance (< 50mΩ).
5. Ultra-Compact Design: A short-body structure allows installation in tight spaces like hand-held devices and small control panels.

• Red (R): Often used for Emergency or Stop functions.
• Green (G): Signals Start, Run, or Safe status.
• Blue (B): Common for auxiliary functions or standby.
• Yellow (Y): Indicates Warning or Caution.
• White (W): Neutral backlight for dark environments.

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

1. Panel Cutout: Drill a 19mm (0.75 inch) hole in the mounting panel.
2. Insert Switch: Place the 19mm-momentary-push-button-switch through the hole from the front.
3. Secure Nut: From the back, tighten the metal hexagonal nut to fix the switch firmly.
4. Wiring: Connect your 120V power and device wires to the 4-pin-screw-terminal-switch using a screwdriver.

Method 1: LED Synchronized with Device

The LED turns ON only when the button is pressed (Status Indicator).

• Wiring: Connect LED (+) to the Output side of the switch, LED (-) to Power Negative.

Method 2: LED Always ON (Backlight Mode)

The LED stays ON constantly to help locate the switch in the dark.

• Wiring: Connect LED (+) directly to Power Positive, LED (-) to Power Negative.

1. What is a 120V Push Button Switch?

A 120v push button switch is a control component designed to handle standard mains voltage in North America and other regions. In industrial settings, these switches act as the primary interface between the user and the machine, controlling the flow of electricity to activate or deactivate specific functions. The metal construction ensures durability against physical abuse and environmental factors.

1. Is this 120V push button switch waterproof?
Yes, it has an IP65 rating, making it protected against dust and low-pressure water jets from any direction.

2. Can I use this 19mm momentary switch for a PC power button?
Absolutely. The momentary-metal-button-switch function is exactly what a PC start button requires.

3. How do the 4-pin screw terminals benefit industrial use?
The 4-pin-screw-terminal-switch allows for a more secure mechanical connection that resists vibration better than traditional soldering.

4. Does FILN offer custom LED colors like purple or bi-color?
Yes, we can customize R/G, R/B bi-color, or even tri-color LEDs to meet your status indication requirements.

5. What does the "Ring Illuminated" design mean?
It means the button has a circular halo light around the actuator, providing a modern look and clear visibility in the dark.

6. Is 304 stainless steel better than brass for this switch?
For highly corrosive environments like marine or food processing, 304 stainless steel is superior due to its rust resistance.

7. Can I get this switch with pre-wired cables?
Yes, FILN provides wire harness customization services to speed up your assembly process.

8. What certifications does this switch carry?
Our switches are fully certified with CE, UL, RoHS, and VDE standards for global compliance.

9. How long is the mechanical life of the FLM19-FS-1-E?
It is rated for over 500,000 cycles, ensuring years of trouble-free operation.

10. Can I operate this switch at 240V?
Yes, the internal contacts are rated up to 250V AC, making it safe for 110V, 120V, and 240V systems.
