The present invention relates to a voltage control structure of a potential therapeutic device, and more particularly to a control structure that can adjust different frequencies and voltages at any time according to user requirements. The potential therapeutic device mainly has a motherboard and a control component. The motherboard is provided with an IC and a high voltage relay； the control component is provided with a plurality of control buttons and an output hole. When assembled, the control assembly is mounted to the side of the motherboard of the potentiometer. The control button can directly adjust the frequency and voltage of the potential therapeutic device to suit different needs of the user, and has considerable practicability.本創作係有關於一種電位治療器之電壓控制結構，特別是指一種可以依據使用者需求，隨時調整不同頻率及電壓之控制結構。該電位治療器主要係具有主機板及控制組件。該主機板設有IC、高壓繼電器；控制組件設有數控制按鍵及一輸出孔。組裝時，將控制組件安裝於電位治療器之主機板一側端。利用該控制按鍵可直接調節該電位治療器之頻率及電壓，以適用使用者之不同需求，具有相當之實用性。
