Abstract

The invention discloses a potentiometer with touch control. The potentiometer comprises a touch induction sheet and a potentiometer body, wherein the potentiometer body is a digital potentiometer body with a control circuit, the touch induction sheet is arranged on the outer surface of the potentiometer body and comprises a flexible circuit board at the bottom and a PP (Propene Polymer) plastic film at the upper part, key-press position marks are printed on the surface of the PP plastic film, the flexible circuit board is provided with touch inductors and a drive chip which is connected with the touch inductors, the touch inductors is in one-to-one correspondence with the key-press position marks, the output end of the flexible circuit board is connected with the control end of the potentiometer, each touch inductor comprises a thermal energy sensing component and is provided with a corresponding LED (Light-Emitting Diode) light source, and the key-press position marks comprise a switching key, a voltage regulating key and a display lamplight strip corresponding to the voltage regulating key. By virtue of the mode, the potentiometer with the touch control has the actions of touch control and state display and is simple and clear in the operation.

Description

technical field [0001] The invention relates to the field of potentiometers, in particular to a potentiometer with touch control. Background technique [0002] The general potentiometer only has the function of mechanical switch and mechanical control, and cannot be switched and adjusted by touch, let alone status display through LED light source. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a potentiometer with touch control, the potentiometer can be controlled by touch through the setting of the touch sensing sheet, and the status information of the potentiometer can be intuitively checked through the setting of the LED. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a potentiometer with touch control, including: a touch sensing plate and a potentiometer, the potentiometer is a digital potentiometer with a control circui...
