The advantage of using a footswitch is simply that it frees up a person's hands for other work while still allowing a human operator full control over switching.
Foot Switches suited for heavy-duty applications such as Machine tools, Sandblasting machines, SPMs, Welding machines.it is used for Hands-Free Switching: You may consider getting foot switches for any application where having "hands-free" switching would be helpful.
