1. Classification according to structural characteristics

Mechanical foot switch: through the mechanical structure such as rack and pinion drive to trigger the internal micro switch or stroke switch, so as to control the circuit on and off, is the most common type, with simple structure, low cost, high reliability advantages, widely used in a variety of industrial equipment and civil electrical appliances .

Inductive foot switch: the use of electromagnetic induction and other principles, when the foot is close to or step down, the sensor generates a signal, and then through the control circuit to drive the switch action, no mechanical contact wear, long life, fast response, but the cost is relatively high, often used in the reliability and health requirements of high occasions, such as some medical equipment, electronic instruments, etc.

Sort by number of pedals

Single foot switch: Only one foot pedal, operated by one foot, is the most common form, suitable for most routine control scenarios, such as controlling the start, stop, etc., of a single device.Two foot step switch: there are two foot pedals, need to operate with two feet, can achieve two different control functions, for example, on some devices, the left foot can achieve one operation, the right foot can achieve another operation, often used in some devices that need to distinguish different operation modes.

Multi-foot switch: there are three, four or even more foot pedals, different feet can achieve a variety of different operating functions, to meet complex control needs, but the volume is larger, the cost is higher, generally used for specific professional equipment or large control systems

2. Classified by operation type

Hold/lock type foot switch: activated when pressure is applied and kept in the contact position until the foot pedal switch is pressed again, it will not change the state, suitable for applications that need to keep the circuit open for a long time, such as continuous operation control of some equipment 2.

Instantaneous foot switch: The foot pedal is required to be under continuous pressure during operation, and once the pressure is removed, the contact will be immediately reset to the original
