The operation principle of 2PSS220-2P is based on an electronic switch composed of transistor and mechanical switch. When the signal voltage of the signals go into the collector of the transistors, the current will flow to the outputs and the 2PSS220-2P will turn on. If the signal voltage disappears, the machine switch is broken and 2PSS220-2P will turn off. In addition, since the transistors can amplify the signal voltage, the 2PSS220-2P is more stable and reliable compared to other two-pole switching systems.

Conclusion

As a two-pole switching system, 2PSS220-2P is widely used in both industrial and residential applications. And its working principle can be described by an electronic switch composed of a transistors and a mechanical switch. Through this explanation, it can be seen that 2PSS220-2P is a reliable and stable switching system and its application field is very wide.
