Abstract
The utility model discloses a speed adjusting switch used for an electric tool. The speed control switch comprises a housing and a push rod. A group of fixed contacts are arranged on the housing. A moving contact sheet matching the group of fixed contacts is arranged on the rush rod. The group of fixed contacts comprise at least three fixed contact bodies arranged to be linear and stair-shaped. The moving contact sheet comprises moving contact monomers in telescopic connection. The number of the moving contact monomers is the same as the number of the fixed contact bodies. An adjusting disc is arranged in the push rod. An adjusting knob is arranged on the push rod. The adjusting knob is connected with the adjusting disc through a synchronous rotating rod. The moving contact monomers are connected with the adjusting disc respectively. The speed adjusting switch is simple in structure. When the speed adjusting switch is in use, first the push rod is pressed downwards and thus the moving contact sheet and the group of fixed contacts are electrically connected, control of the adjusting knob is only needed during speed adjustment, the adjusting knob drives the adjusting disc to act, further the moving contact monomers telescope, thus the moving contact monomers and the fixed contact bodies are electrically connected and therefore the speed adjusting function is achieved. The speed adjusting switch is advantaged by simple operation, low cost, stable and reliable running and good applicability.
