Abstract:
A surface mount variable resistor meets the needs of user for front and rear terminals of an insulating substrate. The surface mount variable resistor includes an insulating substrate 1 with a variable resistor pattern 3 and electrode patterns 5 formed thereon, resistor termination terminal fittings 7 connected to the electrode patterns 5, an electrically conductive slider 15 including a sliding contact 15c that slides on the variable resistor pattern 3, and an intermediate terminal 17 that includes a rear intermediate terminal fitting portion 17a and is electrically connected to the electrically conductive slider 15. The intermediate terminal 17 includes an extended conductor portion 17c and the rear intermediate terminal fitting portion 17a integrally formed with the extended conductor portion 17c. A front intermediate terminal fitting portion 17d located between the resistor termination terminal fittings 7 is integrally formed with the extended conductor portion 17c.
