Toggle switches are electronic components that can control the direction, speed, and magnitude of electrical current. They are used in a wide variety of applications.

One such toggle switch is the 25ET120-S. This is a dual in-line package (DIP) toggle switch that provides a reliable solution for a circuit breaker-type over current protection. It is suitable to be used in a high current switching application up to 120 Amps.

The 25ET120-S toggle switch is an SPST (Single Pole Single Throw) switch, which means it has two contacts, one input, and one output. When the toggle switch is in the "off" position, the input is disconnected from the output and no current flows. When the toggle switch is turned "on," the input is connected to the output and current flows.

The 25ET120-S toggle switch and its application field is mainly mainly used in motor control systems, overload protection and circuit protection. The main advantage of this switch is its ability to handle high current surge and its ability to switch quickly.

The working principle of 25ET120-S toggle switch can be divided into three parts. First, when the switch is in the "off" position, the contacts remain separated, thus blocking the current flow between them. Second, when the switch is in the "on" position, these contacts come into contact, allowing the current to flow through. And third, when the switch is in the "tripped" position, the contacts become separated again, which prevents further current flow.

In conclusion, the 25ET120-S toggle switch is a reliable solution for high current over current applications. They are used in a variety of motor control systems, overload protection and circuit protection applications. The switch\'s three-position design allows for quick and efficient switching, with its contact pair kept separated during the "off" position to prevent current flow and held together during the "on" position to allow current to pass through.
