Abstract
본 발명은 저항값에 해당하는 특정 전기신호에 따라 저항값을 가변시킬 수 있는 전자식 가변저항에 관한 것으로, 소정 저항값을 갖는 다수개의 저항으로 구성되어 있는 저항 모듈과, 다수개의 스위칭 소자를 구비하고 스위칭 동작에 의해 상기 저항 모듈의 전체 저항값을 변화시키는 스위칭부 및, 상기 스위칭부의 스위칭 동작을 제어하는 스위치 제어부를 포함하여 구성된 전자식 가변저항을 제공하여 종래의 가변저항에서 문제시된 가변 스위치 조작에 의해 발생되는 문제점, 즉 물리적 접촉에 의한 마모 및 저항값의 변동 문제를 해결해 주고, 또한 가변저항에 사용되는 스위치가 필요 없으므로 가변저항을 사용하는 제품의 외관을 미려하게 해주는 효과가 있다.The present invention relates to an electronic variable resistor capable of varying a resistance value in accordance with a specific electric signal corresponding to a resistance value, comprising a resistance module composed of a plurality of resistors having a predetermined resistance value, and a plurality of switching elements. It provides an electronic variable resistor comprising a switching unit for changing the overall resistance value of the resistor module by a switching operation, and a switch control unit for controlling the switching operation of the switching unit by a variable switch operation that is a problem in the conventional variable resistor. It solves the problems that occur, namely, wear and physical resistance due to the change in the resistance value, and also does not need a switch used for the variable resistor, there is an effect that makes the appearance of the product using the variable resistor beautiful.
