A mechanical acceleration switch - for accelerations and decelerations - which is arranged in a housing and has a first leaf spring (which carries an electrically conductive contact and a mass and has a first spring stiffness) and a second leaf spring (which carries a second electrical contact and has a greater spring stiffness than the first leaf spring), which switch can be constructed both as a normally-closed switch and as a normally-open switch, switches particularly quickly in the case of the acceleration being above or below a specific acceleration threshold, and greatly reduces contact bouncing.
