- 10 pieces of 12x12 panel PCB momentary tactile switches for reliable user input on 12x12 panels. - Footprint and size: overall 12 x 12 mm, height 4.3 mm, with actuation travel options including 5 mm and 6/7/8/9/10/11/12 mm to match different feel preferences. - Four pin tact switch configuration for straightforward PCB integration and stable mounting. - Variant available: a 12x12x6 mm version for applications requiring a taller lever travel. - Function and performance: momentary action—the switch provides input only while pressed, returning to the resting state when released for clean, repeatable control on panel PCBs. - Compatibility and application: designed for 12x12 panel PCBs; suitable for compact control interfaces, keypads, and small instrumentation panels. - 2-3 practical use scenarios: - Build a compact control panel or keypad for microcontroller or embedded projects, where space is limited and precise momentary input is needed. - Replace worn or non-responsive tactile switches on 12x12 panel PCB assemblies to restore tactile feedback and reliability. - Create a small user interface for DIY instruments or custom hardware, such as measurement rigs, portable devices, or home automation controls. - Key attributes to consider: function (momentary tactile input), compatibility (12x12 panel PCBs), size (12x12 mm footprint, 4.3 mm height; travel options up to 12 mm), configuration (4-pin), and variant availability (12x12x6 mm).
