20PCS 12 x 12 x 4.3 mm Side 2Pin Momentary Tactile Switches for SMD and Panel PCB Mounting Key benefits Reliable tactile feedback for clear on off actions in compact electronic assemblies. Compact footprint saves board space while providing a confident click for user input. Side 2pin design supports easy SMD or panel PCB mounting and straightforward soldering. Pack of 20 provides spare components for prototypes, small production runs, or repairs. Why you need this product Adds a tactile, momentary switch function to control panels, handheld devices, and DIY electronics. Simplifies prototyping by supplying a consistent switch size and mounting style across multiple units. Useful for replacing worn switches or standardizing assemblies where a lowprofile actuator is required. Product highlights Function: Momentary tactile switch with distinct click response for user input. Mounting: Side 2pin configuration compatible with surface mount and panel PCB soldering. Size: Compact 12 x 12 x 4.3 mm profile that fits into shallow enclosures and tight board layouts. Quantity: 20 pieces per pack, identical specifications for uniform performance across circuits. Practical applications Small control panels and instrument interfaces where a lowprofile, tactile button is required. Hobbyist and maker projects such as microcontroller shields, custom remote controls, and enclosuremounted switches. and maintenance of consumer electronics that use similarly sized tactile switches. Installation and compatibility notes Designed for PCB mounting; verify pad layout and hole pattern on your board before assembly. Intended for momentary push operation. Ensure mechanical alignment with your enclosure or panel cutout for reliable actuation. Use standard soldering techniques suitable for SMD components and twopin connectors. Package contents 20 tactile momentary switches, 12 x 12 x 4.3 mm, side 2pin configuration for SMD and panel PCB mounting. This set provides consistent tactile performance and a compact form factor for a variety of electronic projects and repairs.
