The acceleration limit-value switch is provided for motor vehicles and has an inertia body which is seated on a bed and is held in a quiescent position by magnetic forces. Said forces are exerted by a permanent magnet which is provided in the underneath of the inertia body and acts on an iron part. There is a defined air gap between the permanent magnet and the iron part. In consequence, the magnetic force can be set very precisely, so that the critical acceleration or deceleration value at which the inertia body is deflected can be set exactly. The defined air gap also prevents contamination influence.
