12mm Tact Switch

The 12x12mm Through-Hole Tact Switch is a robust, reliability-focused interface component engineered for applications demanding strong mechanical stability and compatibility with traditional PCB assembly processes. Unlike surface-mount variants, its through-hole pin design—typically 2 to 4 pins extending perpendicular to the 12x12mm frame—penetrates the PCB and is soldered on the opposite side, creating a mechanical anchor that resists pull-out forces and vibration-induced loosening. This makes it ideal for high-stress environments like industrial machinery, automotive under-dash controls, and heavy-duty consumer devices (e.g., power tools) where long-term structural integrity is critical.

Featuring a compact yet sturdy 12x12mm frame, the switch balances space efficiency with operational durability. It delivers consistent tactile feedback (actuation force ranging from 200–500gf) and a long service life of up to 100,000 cycles, ensuring reliable performance even with frequent, repetitive use—such as in vending machine buttons or medical device control panels.

To adapt to diverse enclosure and assembly needs, it offers multiple height options: low-profile models (1.5–2.5mm) for slim devices, mid-height versions (3.0–4.0mm) for standard applications, and tall variants (4.5–6.0mm) for designs requiring clearance for thick bezels or protective covers. Additionally, it exhibits strong environmental resilience, withstanding temperatures from -25°C to 85°C and humidity up to 90% RH, making it suitable for both indoor and semi-outdoor use. For engineers prioritizing proven through-hole reliability and versatile design adaptability, this 12x12mm tact switch is a trusted solution.
