19mm High Head Push-Button Switch Stainless Steel 3-Pin Terminal | Momentary & Latching | FILN

The push-button switches (Model: FLM19-HJ-1) are professional-grade 19mm-push-button-switches featuring a prominent high-head-metal-switch design. This high-actuator-panel-switch is specifically engineered for precision and ease of use, making it ideal for users in Europe and America who prefer a larger tactile area. Available in premium stainless-steel-button-switch (Silver) or high-strength black-aluminum-latching-switch (Zinc-Aluminum Alloy), it offers both momentary (self-reset) and latching (stay-put) functions. Certified by ISO9001, CE, VDE, RoHS, SGS, UL, and IP65, FILN ensures each 3-pin-momentary-push-button delivers industrial reliability. This non-illuminated-metal-button is perfect for controlling the on-off state of diverse electrical equipment across automation, marine, and medical industries.

1. Optimized High Head Design: The protruding actuator provides a superior tactile experience, specifically designed for industrial operators in Europe and the USA who often work with large hands or gloves.
2. Material Versatility: Choose between a classic silver stainless-steel-button-switch for hygiene/medical industries or a rugged black-coated aluminum finish for a modern look.
3. Reliable 3-Pin Configuration: Featuring Common (C), Normally Open (NO), and Normally Closed (NC) terminals for versatile circuit control[cite: 1, 2].
4. Durability: Silver contacts ensure low contact resistance and stable conductivity over a long electrical life.

Industry Insight: Indicator Meanings (For LED models)

Although this model is non-illuminated, understanding indicator standards is vital for industrial safety:

• Red: Stop, Emergency, or Danger status.
• Green: Run, Safe, or Normal status.
• Blue: Specific system reset or function.
• Yellow: Warning or Caution.
• White: Power status or auxiliary lighting.

1. Drilling: Drill a 19mm hole on your control panel.
2. Insertion: Insert the high-head-metal-switch from the front of the panel.
3. Securing: Fasten the switch using the metal hexagonal nut from the rear (Threaded Mounting).
4. Wiring: Connect your wires to the 3-pin-terminal-control-switch following the NC/NO logic[cite: 3].

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.

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.

What are Push Button Switches?

Push-button switches are essential mechanical components that allow users to open or close an electrical circuit. High head versions are preferred for accessibility and safety in industrial settings where quick activation is required. The industrial-waterproof-push-button build ensures it withstands high-pressure washdowns or oily workshop conditions.

1. Why is the 3-pin non-illuminated switch better for heavy machines?
Without the complexity of LED wiring, it offers pure mechanical reliability and robust 3-pin connections for high-current loads.

2. Is the high-head-metal-switch available in black?
Yes, we provide both 304 stainless steel (Silver) and zinc-aluminum alloy with a durable black finish.

3. What is the benefit of the 19mm high round head design?
It is designed for tactile ease, making it much easier to press when wearing gloves or in emergency situations.

4. How many terminals does this non-lighted switch have?
This model has 3 pins: Common, Normally Open, and Normally Closed[cite: 1].

5. Is this 19mm-push-button-switches model waterproof?
Yes, it is IP65 rated, making it resistant to dust and water splashes.

6. Can I use the 3-pin configuration as a simple on/off switch?
Yes, by using only the C and NO terminals, you create a standard normally open connection[cite: 3].

7. Do you provide free samples for factory testing?
Yes, FILN provides free samples for qualified B2B inquiries to ensure the product meets your specs.

8. What is the difference between momentary and latching?
Momentary resets immediately after release, while latching stays pressed until clicked again.

9. Are these switches safe for medical devices?
Yes, our 304 stainless steel version is corrosion-resistant and compliant with hygiene standards.

10. Does this 3-pin terminal-control-switch require soldering?
You can either solder the pins or use standard 2.8mm quick-connect female terminals.
