PURPOSE: To provide an acceleration reacting switch capable of avoiding a continuous signal due to the peripheral turning movement of an inertia ball, and finishing the peripheral turning in early time.
CONSTITUTION: An acceleration reacting switch 1 has a container consisting of a lid plate 2 and a housing 5 with a lead terminal 3 penetrating the lid plate 2. A conductive inertia ball 7 is housed in a container, and a contact member 6 is fixed to the end part of the lead terminal 3. The inertia ball 7 is normally positioned in the vicinity of the middle and inhibited from contacting a contact member 6. When receives vibration having a given value or higher, the inertia ball 7 is rotated on the housing rotation surface to contact the contact member 6 to electrically open/close the housing 5 and the contact member 6. Even when the inertia ball 7 begins to peripherally turns along the side wall of the housing 5, the inertia ball 7 contacts a shock-contact part 5C to change a moving direction to make the contact, between the contact member 6 and the inertia ball 7, into noncontinuous contact, thereby preventing the continuous output of an ON signal; and the moving energy of the inertia ball 7 is quickly reduced, thereby preventing the generation of an undesired signal.
