A12AB toggle switches are used in a wide variety of applications which require physical control of an electrical circuit. Generally controlled by an operator, these switches may be divided into two main categories: those that mechanically open and close circuits, and those that electrically interrupt and re-establish them.

Mechanical toggle switches utilize a mechanical mechanism to open and close electrical circuits. A typical switch consists of a lever arm and a contact plate that open and close when the lever arm is displaced. The lever arm is usually actuated by a finger, allowing the user to manually control the circuit. The contact plate then opens or closes the circuit by making contact or breaking contact with the circuit, depending on its position. Common applications for mechanical toggle switches include industrial automation systems, energy management systems, and lighting control systems.

Electrical toggle switches, the second type of toggle switch, use an electrically actuated device to interrupt or re-establish an electrical circuit. Generally, electrical toggle switches contain a control device, such as a resistor or capacitor, which can be adjusted for different current characteristics. As its name implies, an electrical toggle switch operates by having an input voltage applied to it, generally from a switch or from another circuit. This causes the control device, the resistor or capacitor, to bring the circuit into either an “open” or “closed” state, thereby interrupting or re-establishing the circuit. The control device can also be tuned to cause certain effects in the circuit, such as a voltage drop or current amplification. Common applications for electrical toggle switches include amplifiers, filter circuits, circuit breakers, and various other control systems.

Toggle switches are widely used in a variety of applications and have been around since the early twentieth century. While their form factor has changed, their basic functionality and usefulness remains the same. Mechanicaltoggle switches are designed to manually open and close circuits and work by having the contact plate make direct contact with the circuit. Electric toggle switches, on the other hand, are designed to interrupt or re-establish an electrical circuit and are usually actuated by an input voltage from a switch or another circuit. Toggle switches are widely used in industrial automation systems, energy management systems, lighting control systems, amplifier circuits, filter circuits and control systems.
