MICRO SWITCH™ is a brand of electric switch actuated by the physical motion of mechanical devices. The actuation of the switch typically causes an “on” or “off” action. MICRO SWITCH components are generally packaged in a small form factor to allow placement in small spaces.
MICRO SWITCH technology represents the birth of modern electronics and manufacturing, paving the way for millions of products that wouldn’t have been possible without it. The 75th anniversary of MICRO SWITCH technology is an important milestone for our industry, and an excellent example of Honeywell’s strong tradition of innovation.
The original large basic MICRO SWITCH product has paved the way for countless innovations. Snap-action switches were introduced in 1932, hermetically sealed switches for airplane use came onto the market during the 1940’s, and subminiature switches for appliances were introduced during the 1950’s. In fact, research during the 1960’s around the effect of magnetic fields on circuit chips – called the “Hall Effect” – led to the growth of the company’s keyboard design group, eventually giving rise to the sensor business within Honeywell Sensing & Control.
