potentiometer switch
DebonElectorinics are leading potentiometer supplier in china.we arespecializing in producing and developing potentiometers,Encoders,Swithes formany years.With the customers of Behringer,Edifier,Haier,etc.With competiveprice and high qualiy.
Debon potentiometers arerarely used to directly control significant power (more than a watt), since thepower dissipated in the potentiometer would be comparable to the power in thecontrolled load (see infinite switch). Instead they are used to adjust thelevel of analog signals (e.g. volume controls on audio), and as control inputsfor electronic circuits. For example, a light dimmer uses a potentiometer tocontrol the switching of a TRIAC and so indirectly control the brightness oflamps.A potentiometer informally, a pot, is a three-terminal resistor with asliding contact that forms an adjustable voltage divider. If only two terminalsare used (one side and the wiper), it acts as a variable resistor or rheostat.Potentiometers are commonly used to control electrical devices such as volumecontrols on audio equipment. Potentiometers operated by a mechanism can be usedas position transducers, for example, in a joystick.
