12x12x7.3mm Square Tactile Push Button Switch with Round Caps (Multi-colour) – 6-Pin Momentary PCB Micro Switch for DIY Projects, Arduino

Product Description The Pro3D 12x12mm Square Tactile Switch is a robust and highly versatile input component, specifically designed for user-facing control panels. While the base is a standard 12mm square, the unique 7.3mm height includes a specialized square plunger designed to securely hold the included Round Color Caps. These caps not only provide a professional finish but also increase the surface area of the button, making it significantly more comfortable for frequent use. This kit is a favorite for the team at Robogears Pvt Ltd when building custom handheld controllers or educational robotics kits where color-coded inputs (like Red for Stop, Green for Go) are required.

Key Highlights

• Interchangeable Color Caps: The set includes a variety of colored caps that snap firmly onto the square stem, allowing you to easily categorize functions on your control board.

• Professional Panel Look: Using these switches with the included caps allows the buttons to sit flush or slightly protrude through an enclosure, giving your Robogears prototypes a retail-ready appearance.

• Standard 12mm Footprint: Despite the larger size compared to 6mm micro-switches, it maintains a standard layout that fits into most high-power tactile switch footprints on a PCB.

• Crisp Click Response: Features a high-quality internal metal dome that provides an audible "click" and clear tactile feedback, ensuring the user knows the button has been pressed.

• 4-Pin Mechanical Stability: The four-pin configuration ensures the switch remains stable and level on the PCB even when subjected to off-center or heavy-handed presses.
