Description
The TK-045C Tact Switch (4.5×4.5mm) is a versatile, high-precision input component designed for a wide range of electronic and consumer applications. Engineered to provide a crisp, distinct “click” with every actuation, this switch ensures clear user feedback, making it ideal for devices where tactile reliability is essential. Its robust construction features silver-plated contacts for excellent conductivity and insert-molded terminals that prevent flux contamination during the soldering process.
The TK-045C is built for flexibility and ease of integration, featuring a snap-in mounting terminal and an optional ground terminal for enhanced stability and electrostatic protection. Whether you are designing compact audio-visual products, medical equipment, or high-use remote controls, the TK-045C offers the durability (rated for 100,000 cycles) and performance required for professional-grade hardware.
