Self-Locking vs. Self-Reset — What's the Difference?
| Mode | Behaviour |
|---|---|
| Self-Locking (Latching) | Press once → button locks in, LED on, equipment powered. Press again → button releases, LED off, equipment off. |
| Self-Reset (Momentary) | Press and hold → LED on, equipment powered. Release → button springs back, LED off, equipment off. |
Terminal Guide
- A / + : Positive pole of the LED
- LED / – : Negative pole of the LED
- NO : Normally Open — circuit is open until button is pressed
- NC : Normally Closed — circuit is closed until button is pressed
- C : Common terminal
Wiring Overview
NO + C configuration: Circuit stays open by default; pressing the button closes the circuit and activates the load.
NC + C configuration: Circuit stays closed by default; pressing the button opens the circuit and deactivates the load.
General Wiring: Connect the positive power supply to the Common (C) terminal and one LED pin; connect the NO terminal to the positive pole of your equipment. Connect the negative power supply to the other LED pin and the negative pole of your equipment.

Frequently Asked Questions
Q: What is the difference between self-locking and self-reset push button switches?
A: A self-locking (latching) push button switch stays in its pressed position after you release your finger — the LED remains on and the circuit stays active until you press it again to release. A self-reset (momentary) push button switch automatically springs back to its default position the moment you release your finger, cutting the circuit and turning off the LED. Choose self-locking for on/off power control and self-reset for momentary trigger functions like doorbells or machine start buttons.
Q: Which mounting size should I choose — 12MM, 16MM, 19MM, or 22MM?
A: The size refers to the panel-mount hole diameter required. Measure your enclosure's existing hole or drill a new one to match: 12MM for compact panels, 16MM for standard DIY and industrial use, 19MM for a slightly larger bezel footprint, and 22MM for heavy-duty or high-visibility applications. All sizes share the same CE-certified stainless steel waterproof construction.
Q: What voltage should I select for my application?
A: These switches are available in three voltage ratings: 3–6V DC (ideal for Arduino, Raspberry Pi, and low-voltage LED circuits), 12–24V DC (suitable for automotive, marine, and industrial DC systems), and 220V AC (for mains-powered household or commercial equipment). Always select a switch rated at or above your circuit's operating voltage for safe, reliable performance.
Q: Is this push button switch truly waterproof?
A: Yes. The stainless steel body and sealed construction provide effective moisture resistance, making these switches suitable for outdoor control panels, marine dashboards, and wet-environment industrial enclosures. The waterproof rating helps prevent corrosion and short circuits caused by water ingress.
