Foot switch

Switches that are operated by a user's foot are desirable when the user's hands are otherwise occupied. For example, foot switches are often used to trigger the delivery of laser energy in a medical laser system. Industrial machines which are operated by an operator frequently require remotely located hand operated or foot operated switches for safe operation. Foot actuated pneumatic switches are often used in the food equipment industry to obtain precise hands-free operation of the desired food equipment. A foot switch can also used in the operation of a computer and allows the operator to duplicate keyboard entries which would normally be made by the hands of the operator. While various types of foot operated switches are commonly used, mechanical or pneumatically actuated switches are the most popular. Mechanically actuated foot switches include the plunger or push button type, or the tumbler type foot switches. Pneumatically actuated foot switches typically comprise a deformable pneumatic bulb, or air cushion, which is deformed by the foot of the user to operate a remotely located switch mechanism.
