This section provides overview, applications, and principles of foot switches. Also, please take a look at the list of 24 foot switch manufacturers and their company rankings.
A foot switch is a switch that turns power and electrical signals on and off by foot motion. By switching on and off with a foot action, work that is normally done by hand can be done more efficiently.
When selecting a foot switch, it is necessary to confirm that it meets the conditions of use, taking into consideration the type of load and electrical rating. Loads include resistive loads and inductive loads, and their voltage (AC and DC) and current ratings must also be checked to ensure compatibility. Some types of inductive loads have a large difference in starting current and holding current, so care must be taken.
Foot switches are switches that turn on and off with a foot motion and are generally used in various fields as external input devices for digital equipment.
They are used in various fields, such as measurement and medical equipment, amusement equipment, nursing care, and welfare equipment, and industrial machineries such as machine tools and presses.
The basic function of a switch is to turn on and off by foot movement, but there are various types in terms of shape and function depending on the industry in which it is used and the specifications required.
This is an on/off operation using a foot switch, but the switch is operated by stepping on it with the foot. The foot switch is divided into two types, momentary type, and alternate type, according to the difference in the change in electrical connection state caused by the footstep action.
Momentary type footswitches, as the name implies, are momentary footswitches, meaning that they turn on only while the switch is depressed.
An alternate footswitch, on the other hand, means "alternating," meaning that when you step on the switch, it turns on and stays on even when you take your foot off. When you step on the switch again, it turns off and remains off when you take your foot off. Each time you step on the switch, it alternates between on and off.
There are also latch-type and unlatch-type footswitches that differ in mechanical operation. In the latch type, when you step on the switch to turn it on, the switch remains in the depressed position. When you step on the switch again, the switch returns to its original position and turns off. On the other hand, unlatched type switches are those that return to their original position once you step on them, whether they are turned on or off.
