Abstract
Disclosed is a lever switch being capable of providing predetermined electrical operational instructions by rotating the first rotary knob 3 and the second rotary knob 5 about the axis respectively, characterized in that a first detent mechanism 21 is provided on the distal side of the control lever 1 for providing detention against rotational operation of the second rotary knob 5, a lever guide 19 formed with a lever guide hole 20 is provided on the control lever 1, a lever shaft 39 extending from the distal side to the proximal side of the control lever 1 is disposed in the lever guide hole 20, the first rotary knob 3 is connected to the distal side of the lever shaft 39, a control rod 43 is provided for providing the electrical operational instructions on the proximal side of the lever shaft 39, and a second detent mechanism for providing detention against the rotational operation of the first rotary knob 3 is provided between the proximal side of the lever guide 19 and the control rod 43. The lever switch enables prevention of malfunction of the first and second rotary knobs while downsizing.
