Classification of thumbwheel potentiometer with switch

Multi-loop precise thumbwheel potentiometer with switch: In some industrial control and instrumentation circuits, high adjustable precision is usually required. In order to meet the needs of production. This kind of circuit adopts a multi-loop adjustable potentiometer. The finger wheel potentiometer with switch has a wide range of step-by-step. High accuracy.            Classification of Resistance Materials            

Carbon film type: Carbon film is used as resistance film.            

Ceramic Gold Film: Cermet film made of ceramic and metal is used as resistance film.            

Wire-wound type: The resistance is made of metal wire-wound. Compared with carbon film or ceramic film, it can withstand higher power.            

Construction and classification of thumbwheel potentiometer with switch           

Rotary: Common form. The usual rotation angle is about 270-300 degrees.            

Single-loop: Common form.            

Multi-loop type: Used in situations requiring precise adjustment.            

Linear sliding type: Usually used in mixers, it is easy to immediately see the volume position and fade in and out control.
