The 12x12x4.3H 4-Pin Tact Switch is a highly versatile momentary button engineered for dependable circuit activation in a wide range of electronic devices. Featuring a substantial 12mm x 12mm base for superior stability and a standard 4.3mm height (H), this switch provides a comfortable tactile feel and clear mechanical "click" upon depression. Its durable black housing and 4-pin through-hole design make it a staple component for both professional PCB manufacturing and high-end DIY hobbyist projects.
Versatile 4.3mm Height: The mid-range 4.3mm profile is compatible with most standard button caps and enclosure depths.
Stable 12x12mm Footprint: The large square base ensures the switch remains firmly anchored to the PCB, even under repeated or heavy use.
Secure 4-Pin Mounting: Features four reinforced metal pins designed for stable through-hole soldering and consistent electrical conductivity.
Reliable Momentary Operation: Functions as a Single Pole Single Throw (SPST) switch, completing the circuit only while the button is held down.
Tactile Mechanical Feedback: Provides a crisp, audible, and physical response to confirm every press, improving user accuracy.
This 12x12x4.3mm Tactile Button is ideally suited for:
Home Appliances: Main power toggles or function buttons for microwaves, coffee makers, and washing machines.
Industrial Control Units: Durable interface buttons for PLC modules, hand-held scanners, and diagnostic tools.
Gaming & Entertainment: Reliable input triggers for arcade controllers, console resets, and DIY gaming rigs.
Prototyping & Education: A robust component for advanced Arduino, Raspberry Pi, and robotics projects requiring a larger button surface.
Dimensions: 12mm x 12mm (Base) x 4.3mm (Total Height).
Pin Count: 4-Pin through-hole.
Color: Black.
Switch Type: Momentary Tactile.
Mounting Type: PCB Through-Hole.
Is the 4.3mm height measured from the PCB?
Yes, the 4.3mm height is the "H" dimension, measured from the base of the black plastic housing to the top of the round actuator button.
Are all 4 pins unique circuit paths?
No, the pins are typically connected in two pairs internally. This design is used to provide better physical anchoring on the PCB rather than four separate electrical signals.
How does this differ from the 12x12x2H model?
The main difference is the height. The 4.3H model is standard for most applications, while the 2H model is ultra-slim for very thin device housings.
