Rocker switches are one of the most common and important types of toggle switches that one finds in vehicles, computers and other electronic devices. A22KP-CA is one such model which is a Single Pole Single Throw (SPST) on-off switch with a unique design of a long rocker body and a flat actuator button to make it easy to operate with single finger. Here we discuss about the application field and working principle of A22KP-CA:

Application Fields of A22KP-CA

The A22KP-CA is a waterproof, dust-proof and shockproof rocker switch having vibration resistance due to its special design. Therefore, it is very suitable for most of the vehicles, especially in demanding applications like off-road, agricultural and outdoor equipment. It is also find applications in computers, temperature control systems, medical equipments, audio systems, power systems, lighting and many other devices. The A22KP-CA has two different designs – one is the front panel mount with pin type connection and the other is printed circuit board mount. Due to the good life ratings and variety in connections, the A22KP-CA is one of the most widely used rocker switches.

Working Principle of A22KP-CA

The working principle of A22KP-CA is simple and it works for both on/off as well as on/off/on configurations. When the actuator button is in normal position, the resistance between the two terminals remains equal and the circuit is open. When the actuator button is depressed, the resistance between the two terminals changes and the circuit is closed. The A22KP-CA uses snap action mechanism for switching mechanism, which eliminates any mechanical wear and also provides faster switching action and better life ratings of the component.

The A22KP-CA is rated to carry up to 16 amps of current at 250V AC. It has a DC rating of 0.3 to 6 amps at 12V or 24V depending on the load. It works perfectly in reasonable temperature range of -25°C to 85°C. It is extremely reliable and has a long life span of more than 10000 cycles of operation. It is also fused with a stainless steel spring, making it highly resistant against vibrations, shocks, impacts and water drops.

To sum up, the A22KP-CA is a durable and reliable rocker switch with reasonable cost and excellent performance. Its different design and connection options makes it suitable for wide range of applications from automotive to medical. Its long life ratings and quick switching mechanism makes it a preferred choice for several applications and it has been used in variety of products due to its remarkable capability.
