Abstract
In an acceleration switch, a magnetic contact opening/closing member is disposed at a horizontal initial position above a holding member. The end portion of the contact opening/closing member is pushed upward from the initial position by a ball that rolls along the tilt surface of the holding member with an inertia. First and second leaf springs are disposed to oppose each other on rolling and non-rolling sides of the ball through the holding member, and have upper free ends for sandwiching two end portions of the contact opening/closing member at the initial position. At least the first leaf spring is made of a conductive material and imparted with properties to swing in a direction to come close to the second leaf spring. When the contact opening/closing member is at the initial position, the first leaf spring is pressed by the contact opening/closing member in a direction to come close to an electrode plate against the swing properties and comes into contact with the electrode plate. When the contact opening/closing member is shifted from the initial position, the first leaf spring swings in a direction to separate from the electrode plate in accordance with the swing properties to be disconnected from the electrode plate.
