Abstract
A groove-like recess, substantially V-shaped, extending vertically is formed on the outer circumference of an operation shaft, and a projection engaging the recess is provided on a guide hole, namely the inner circumference of a hollow pipe. Such makeup provides an automotive push switch that reduces an impactive force caused when the recess hits the projection within the movable range of the operation shaft, by decomposing or dispersing the force according to the inclination angle of the slope, and so does the hitting sound.
