This invention is directed to providing a handle switch which is easy in operating a horn switch and also can be easily distinguished from other switches.In a handle switch 30 of a vehicle, a horn switch 32 is disposed at a position which is overlaid on an axis line (D) of a handle grip 10 when a housing 60 is projected from a driver's front view direction and also on the vehicle body rear side further than other switches. Other switches including an optical-axis changing switch 31 and a turn signal switch 33 are disposed so as to deviate vertically with respect to the horn switch 32. The horn switch 32 is formed so as to be longer in the axis line direction of the handle grip 10, swinging about a swing shaft 36 installed at the end closer to the handle grip 10 by being pressed toward the vehicle body front side. The horn switch 32 is increased in area of an operating surface 32e, a clearance between upper and lower contour lines and a protruding amount from the housing 60, respectively, from a vehicle body outward part 32d toward a vehicle body inward part 32c.
