U21K9AV2QE is a toggle switch which is a type of switch used to control the partial or total connection of a circuit. It enables the flow of current into a circuit when the toggle button is in an on position or disconnects the flow when the toggle button is in an off position. It is an electro-mechanical device that is either manually or remotely operated. The switch is commonly used for selecting source in audio-visual equipment, for lamps and for various other domestic appliances. It also finds use in various industrial systems.The construction of a toggle switch varies according to the application. However the working principle remains the same and requires a basic understanding of the internal components. The core of a toggle switch contains a spring loaded mechanism and two metal contacts. The toggle switch consists of a pair of contacts that are connected and disconnected when the switch is turned on and off. To power up the device, a current must be supplied to the terminals that are connected to the switch mechanism.When the switch is turned on, the electrical current flows through the terminals and this triggers an electromagnet which pulls on the switch’s spring-loaded mechanism. This mechanism is connected to a toggle button which, when pressed, pushes the toggle switch into an ‘on’ position and allows the current to flow uninterruptedly into the next component in the circuit. When the switch is in an ‘on’ position, the electrical current is able to flow, whereas when the switch is in an ‘off’ position, the current is not able to flow.As far as application fields are concerned, toggle switch can be used in a variety of settings. It is commonly used in vehicles, motorcycles, scooters and other motorised vehicle in order to control certain features on the vehicle such as seats, windows and lights. Toggle switches are also common in household electrical wiring to control floor or table lamps, wall and ceiling lights, and appliance motors.In audio systems and other media equipment, toggle switches are often used to select the source of audio. An ‘on’ position usually allows a speaker or amplifier to access a speaker, headphone jack, or record player. Industrial environments often usetoggle switch too as they are reliable and sturdy. For instance, toggle switch is widely used in industrial motors and machines in order to start and stop the operation, set running modes and adjust the speed parameters.In summary, a toggle switch is a type of switch that is used to control a partial or complete connection in a circuit. It is composed of a spring-loaded mechanism and two metal contacts. Toggle switches can be used in many settings and applications – e.g. in vehicles, audio equipment, household electrical wiring and industrial environments.
