6x6x5mm Tactile Push Button Switch – 4-Pin Momentary PCB Micro Switch for Arduino, ESP32, and Prototype Electronics (Standard Height) (Pack of 3)

Product Description The 6x6x5mm Tactile Switch is the industry-standard "low-profile" momentary button. With a total height of just 5mm, it is designed for surface-level interaction on PCBs where a flush or near-flush finish is required. This switch is the "bread and butter" of the electronics prototyping world and a vital part of the Robogears Pvt Ltd toolkit. Its 4-pin design provides excellent mechanical stability, ensuring the switch stays firmly seated on the board during repetitive use in consumer electronics, remote controls, and microcontroller-based projects.

Key Highlights

• Universal Standard Height: The 5mm height is the most common size, making it highly compatible with standard plastic button caps and existing enclosure designs.

• Breadboard & PCB Ready: Features pins spaced specifically for 2.54mm (0.1") pitch, allowing it to snap directly into solderless breadboards for rapid R&D.

• Superior Mechanical Stability: Although it functions as a 2-terminal switch, the 4-pin footprint prevents the component from tilting or breaking off the solder pads under heavy thumb pressure.

• Clean Tactile "Click": High-quality internal stainless steel domes provide a sharp, audible feedback sensation, reducing the chance of accidental or incomplete presses.

• High Chemical Resistance: Constructed from high-temperature PBT/Nylon, making it resistant to flux and cleaning agents used during the soldering process.

Prototyping & Installation Tip (Standard Wiring) When wiring this for an Arduino or ESP32 at Robogears, remember that the pins are connected in pairs. If you look at the bottom, the two pins on the same "flat" side are already connected. To make the switch work, you must connect your wires to the pins on opposite sides of the plastic body. Using a 100nF capacitor across the switch pins can provide "hardware debouncing," ensuring your software doesn't register a single click as a double-click.
