What are the switching devices?

The switching device is any mechanical, electrical, pneumatic or hydraulic device designed to open or close the electrical circuit. However, this is a general description and term switching devices can be properly applied to a number of devices and applications that fall outside these boundaries. When applied to the electrical circuits, the switching device usually refers to any device that causes or breaks the electrical circuit. These devices can be equally diverse when operating and appearance as a simple switch on the bed lamp on the circuit breaker in air weighing several tons. However, everyone performs the same basic function.

Electric switching devices consist of sets of contacts that open and close when activating the device. For each line, phase or part of the circuit, they are designed for switching. For example, a simple circuit breaker in the home distribution plate will have one set of internal contacts of a similar bed. A unit for Earth's leakage in the same board should usually dVA, one for a living line and one for a neutral line.

Small low voltage relays commonly used in the automotive industry to switch the driving lights, indicators and fog lamps, are classic examples of multi -contact switching devices, as they usually have between six and eight sets of contacts. Larger examples of heavy products are common in industrial applications, where they are used as appetizers for electric motors and other heavy -dollar discharge devices.

These devices are operated in different ways, the simplest are manual switches such as home light switch. Others are remotely operated by means of an electromagnetic coil to activate the switch. Pneumatic or hydraulic switches are also relatively common and use either air or oil pressure to open or close.

switching devices are also common in the IT field and although the bendAdvance principle still applies, their function is very different from their high voltage electrical counterparts. Data switching is the process of directing several data sources to a single output point or identifying and diverting data signals between points. These processes differ from electrical varieties in that the actual switching is performed at the level of electronic components and not with heavy mechanical switches.

The

switching devices are found in many different common devices. It is extremely unlikely that someone will go through the day without using at least one of them without the other.
