Snap action refers to a type of mechanical switch that toggles between its two stable states when certain level of force is applied to it. This action occurs quickly, which is why the switch is sometimes referred to as a "release" or "bounce" switch. Limit switches are electro-mechanical proximity devices that sense the presence or absence of an object and can be used to monitor position in a variety of applications. They are available in the form of single-pole and double-pole units.

The D4C-2520 limit switch from Omron Automation is a snap action switch ideal for industrial or communications applications. It is designed for an array of applications requiring a compact and reliable switch to detect presence or inactivity in self-monitoring or operating functional devices. The switch is capable of low-mechanical force operation which results in a longer life span.

This limit switch utilises a single-pole, normally-open contact arrangement that provides hysteresis, allowing for a dependable switching mechanism when used in equipment requiring high reliability and precision. With its built-in snap action mechanism, it responds quickly in response to varying temperatures. Its low-mechanical operation means its contact life can reach up to 25 million operations.

The D4C-2520 limit switch is powered by a 0.2 to 0.6A power supply and is capable of tolerating a temperature range of -10°C to 50°C. It can be used with a range of accessories, such as housings, hoods and actuators, depending on the requirements of the application. Its dimensions of just 27mm x 25mm x 25mm make it suitable for applications requiring a space-saving design.

The limit switch works on the principle of external actuation, which means that its contact closure or opening is triggered by external force. The switch consists of a plunger and a switch body, the latter of which contains an enclosed spring. When the plunger is actuated, it compresses the spring and causes the switch to "snap" or change state. This action releases the energy stored in the spring for small, fast and reliable changes in contact state.

The D4C-2520 limit switch is a reliable and economical switching solution for a variety of industrial and communications applications. Its small size, low power consumption and long-life contact rating make it an ideal choice for applications such as motor control, switching, equipment monitoring and more.
