A foot switch, also known as a pedal switch, is a switch that is operated by the foot. It is commonly used in musical instruments such as guitar effects pedals and electronic keyboards, as well as in industrial settings for controlling machinery or other equipment.

A foot switch usually consists of a pedal or button that is pressed down with the foot to activate the switch. The switch can be a simple on/off switch, or it can be more complex, with multiple positions or functions. Foot switches can be connected to devices using a cable or wirelessly through Bluetooth or other wireless protocols.

Foot switches are often used by musicians to control various effects or functions while playing their instruments. For example, a guitarist may use a foot switch to turn on or off distortion or delay effects during a performance. In industrial settings, foot switches can be used for safety reasons, allowing operators to keep their hands free while controlling machinery.

Industrial foot switches can also enable workers to handle multiple tasks at the same time, which is a means to improve the overall efficiency of industrial automation.
