Description

The TK-037 Tactile Switch is a high-performance film-type switch engineered for precision and longevity. At the heart of this switch is a high-quality stainless steel metal dome, which provides excellent tactile feedback and ensures a long operational lifespan. Designed for seamless integration into modern electronic devices, the TK-037 utilizes the natural resilience of the metal dome to ensure automatic, consistent return-to-state performance after each press.

With its micro-miniature form factor of 3.7 x 3.7mm and low-profile height options (0.35H/0.38H), this switch is an ideal choice for high-density printed circuit boards (PCBs). It features a snap-in mounting design that facilitates direct PCB installation while providing effective protection against electrostatic discharge (ESD).
