Omron Corporation (オムロン株式会社) is a Japanese manufacturer whose product range formerly included a number of keyboard switch types, including mechanical, Hall and reed switches. Having left the keyboard switch market, they recently they re-entered it, after Logitech partnered with them to produce the Romer-G switch that was introduced in 2014. The B3K series created for Logitech has since been used by both Creative and Metadot.

Omron was founded as Tateisi Electric Manufacturing Co. in 1933, becoming Tateisi Electronics Co. (立石電機株式会社: Tateishi Electric Co., Ltd.) in 1948. The name Omron (オムロン: o-mu-ro-n) was trademarked in 1959. In 1968, the English-language name became OMRON Tateisi Electronics Co., which is how patents are listed in English, while in Japanese the name remained as 立石電機株式会社. The current name of Omron Corporation was only adopted in 1990.
