Switch, the structure characteristics of the encoder switch, encoders have two fixed end, the resistance of the body by manually adjusting shaft or sliding handle, change the position of the moving contact on the resistor body, has changed the moving contact between as a fixed end resistance, so as to change the size of the voltage and current. Switch, the encoder is a kind of adjustable electronic components. It is formed by a resistor and a rotating or sliding system. When the resistance between two fixed electric shock, plus a voltage by rotating or sliding system change the location of the contact on the resistor body, between the fixed contact and moving contact can be a relationship with the moving contact position with a certain voltage. It is mostly used as a divider, then switch, the encoder is a four-terminal element. Is basically a slide rheostat switch, encoder, there are several kinds of style, commonly used in speaker volume switch and laser power size adjustment switch, the encoder is a kind of adjustable electronic components. Variable resistor for partial pressure. On the resistance of the bare body, tightly holding up one or two movable metal contact. Contact position to determine the resistance between both sides and contact resistance. According to the material points wire wound, carbon film, solid core belt switch encoder; According to the output to the input voltage ratio and rotation Angle of the relationship between points and linear encoder switch ( A linear relationship) , function switch encoder ( A curve relationship) 。 Main parameters of resistance, tolerance, and rated power. Widely used in electronic devices, in sound and receiver for volume control. Shanghai electronics specializing in the production of switch encoder 26 years, relying on 26 years professional experience, the encoder more became some of the world famous enterprises designated products. Customers throughout the world, the product has been, SAMSUNG, SANYO, PANASONIC, TCL, MICROSOFT, rambler, chaoyang, FORYOU, Huayang gm) Desai, navigation, west wei, song, backgammon, galanz, midea and other well-known enterprises at home and abroad. Looking for looking for electronic encoder manufacturers.
