The rectifying part and the leading end of the direct sliding potentiometer

1. Collector (also known as conductive ring)

The collector is an electrical connecting member between the outlet end and the contact reed. The collector has good electrical conductivity, small contact resistance with the reed, high mechanical strength and good wear resistance. Usually brass, aluminum or aluminum alloy; Some direct - slip potentiometer materials need to be protected by electroplating. The collector of metal-glass glaze potentiometer is formed by firing and seepage of silver layer on the porcelain substrate.

2. terminal

The outlet end is a component connecting two fixed ends of the resistance body and a variable end of the brush with the external circuit. The potentiometer with switch and switch lead ray. Tap potentiometer and tap lead end, it is in the effective electrical stroke of a point of the lead wire. All the leads and the interior should have good electrical connections. The outlet end shall have good electrical conductivity, corrosion resistance and oxidation resistance, and a certain degree of bending, tensile mechanical strength and good weldability. The common materials used at the outlet end are brass and iron-nickel alloy, etc., and the electroplated nickel, tin, silver and gold are often used as the protective layer for the direct potentiometer.
