<p>PURPOSE:To obtain a changeover switch whose two lead switch arrangement does not require much space, by connecting in parallel the 1st lead switch which connects with the 1st resistance in parallel, with the 2nd lead switch which connects with the 2nd resistance in series, and at the same time installing them in parallel. CONSTITUTION:A motor 10 rotation number changeover switch is provided. This consists of a pair of lead switches 41, 42 fitted in parallel to a frame at a movement conversion mechanism within a housing 1, a pair of magnets 31, 32 fitted to the inner surface side of a handle 3 by means of a fitting frame 33, a resistance 43 connected with the switch 41 in parallel, and a resistance 44 connected with the switch 42 in series. And both lead switches 41, 42 are connected with each other in parallel, and in addition, magnets 31, 32 at the handle 3 are fitted slightly shifted positions in a handle 3 slide direction. As a result, both lead switches 41, 42 are arranged in a limited space taking advantage of dead space.</p> |
