<p>PROBLEM TO BE SOLVED: To provide a wiring apparatus capable of using related components such as a conventional mounting frame 70 while using a new standard variable resistor 30 (substitute) in which no on-off switch mechanism is incorporated.SOLUTION: As a case body 10 and a lid body 11 forming the outer shape of a wiring apparatus, the same ones as used for a conventional wiring apparatus in which a conventional variable resistor 130 (conventional product) is incorporated are used. The difference between the height dimensions (a height dimension from the bottom surface to the end of a rotary shaft 32) of new and old variable resistors 30 is adjusted by a shaft adjusting unit 60 fit on the end portion of the rotary shaft 32 in the variable resistor 30. In other words, the shaft adjusting unit 60 is adjusted to a length at which the end portion projects outward through a bearing hole 11a of the lid body 11 and a knob 80 for rotational operation can be fit on the end portion in a state where the base end is connected with the end portion of the rotary shaft 32. Furthermore, the shaft adjusting unit 60 includes means for applying sliding resistance to the rotational operation by the knob 80 and means for turning on and off a microswitch 50 at a predetermined rotational angle.</p> |
