Understanding Foot Switch Tech
Foot switches have been around for a long time. They're useful in home,
commercial and industrial settings. For example, my wife is a
professional seamstress. Her sewing machine has a foot switch or pedal
that controls both on/off functions and machine speed.
In the industrial environment – my home away from home – the controls are built a bit differently. They need to stand up to more abuse. But, the same concept applies — using the foot to free up the hands for other duties.
