This conductive liquid switch is a novel mercury switch to be mounted on a horizontally moving apparatus such as an automobile and clearly distinguishes the condition of acceleration caused during the abnormal motion period in which the automobile is subjected to sudden acceleration or deceleration or skidding which is dangerous for the automobile from the conditions of acceleration caused during the period in which the automobile is parking, or is subjected to the usual acceleration or deceleration, or is travelling at a normal speed, thereby to open or close at least one electric circuit. This switch is activated when a predetermined value of acceleration is applied thereto in one direction for a predetermined period of time before the moving apparatus is tilted at a dangerous angle or turned upside down owing to a collision or the like, that is, the position of the moving apparatus is not different from the usual position thereof, thereby to operate an occupant's protection device such as a safety belt, an air bag, or a safety net.
