What Are Switching Devices

A switching device is any mechanical, electrical, pneumatic or hydraulic device designed to open or close an electrical circuit.

This is generic description though, and the term switching devices can be applied correctly to a number of devices and applications that fall outside those boundaries. When applied to electrical circuits, the term switching device typically refers to any device that makes or breaks an electrical circuit. These devices can be as diverse in their operation and appearance as a simple switch on a bedside lamp to a captive air circuit breaker weighing several tons. They all fulfill the same basic function, however.

Electrical switching devices all consist of sets of contacts that open and close when the device is activated. There are one set of contacts for each line, phase or part of the circuit they are designed to switch. And more common in larger heavy-duty industrial applications are multi-contact switchgear applications.

These devices operate in a variety of ways, the simplest of which is a manual switch. For example, 202E, 501, 515, 238 series manufactured by our company. Public places are ideal for infectious diseases such as COVID-19, and to be more safe and adaptable to the current environment, we have also introduced a range of non-contact switches. For example: 505, 512, 602, 238M series etc., just wave your hand to open the door.
