PURPOSE: A lead switch assembly is provided to prevent damages of the glass tube constituting the lead switch assembly by permitting impacts to be uniformly distributed all over the glass tube having an extended diameter. CONSTITUTION: A lead switch assembly comprises a lead switch supporter(4) for protecting a glass tube(3) and guiding a magnetic lead extracting direction; the glass tube embedded in the upper space of the lead switch supporter; a magnet lead(2) arranged to penetrate through both sides of the glass tube and extracted in the rectangular direction with respect to the lengthwise direction of the glass tube; and a bending portion(200) arranged at a side of the magnetic lead extracted in the rectangular direction with respect to the lengthwise direction of the glass tube so as to absorb impacts. The glass tube has both ends each of which has an extended diameter. The bending portion and a glass tube expanded portion(300) have escape grooves(400).
