Key Tronic (NASDAQ: KTCC) is a contract manufacturer. Founded in 1969, its core product group initially included keyboards, mice and other input devices. KeyTronic now specializes in PCBA and full product assembly, plastic molding, precision metal stamping, fabrication and finishing, and engineering services with products ranging from simple consumer devices to complex, high end commercial and industrial electro-mechanical products. Key Tronic operates worldwide with activities in the United States, Mexico, and China. After the introduction of the IBM PC, Key Tronic began manufacturing keyboards compatible with those computer system units. Most of their keyboards are based on the 8048 microcontroller to communicate to the computer. Their early keyboards used an Intel 8048 MCU. However, as the company evolved, they began to use their own 8048-based MCUs.
