Variable resistor with switching mechanism |
摘要 |
A variable resistor having a switching function includes a base plate, a first electrode formed on the base plate, a second electrode formed on the base plate, a third electrode formed on the base plate, and a fourth electrode formed on the base plate simultaneously with the formation of the second electrode. A resistive element connects electrically the first and the second electrodes, a first switching element is provided and includes two brushes which slide on the surfaces of the third electrode and the resistive element, respectively. A second switching element is movable together with the first switching element and includes two brushes which slide on the surfaces of the first electrode and the fourth electrode, respectively.
