NON-SILVER TERMINAL VARIABLE RESISTOR

摘要

A non-sliver terminal variable resistor is provided to simplify a circuit by printing only resistor when printing a PCB(Printed Circuit Board) of a variable resistor. A PCB includes a resistor(11), a standard terminal(12), a lead(13) and an auxiliary resistor. The standard terminal is connected to the both end portions of the resistor, and the lead is connected to the standard terminal. The auxiliary resistor is printed between the standard terminal and the lead, and a rotary shaft by which a insertion protrusion is inserted into a through hole(16). A connector operates by the operation of the rotary shaft, and a contactor(30) measures a resistor value corresponding to the portions where the resistor is contacted with a contact point. A transferring shield which transfers resistor value to the outside is formed at a shield plate in one body.
