Acceleration limit switch

An acceleration limit switch, comprising:

• a housing;
• a ball-shaped inertia body made of a ferromagnetic material and having a housing bridge;
• a permanent magnet;
• a printed circuit board with said ball-shaped inertia body being maintained in a resting position by said permanent magnet spaced from said printed circuit board, said, printed circuit board having two contact elements symmetrically positioned with respect to each other, said printed circuit board acting as a cover for said housing;
• an elastic, conductive plastic mat being mounted between said ball-shaped inertia body and said printed circuit board, said mat being deformed when impacted by said ball-shaped inertia body, thereby connecting said two contact elements;
• a ring-shaped support surface for supporting said conductive plastic mat, said ring-shaped support surface being contained within an interior space of said housing with said interior space being symmetrical;
• elastic hooks being formed on said housing;
• and,
• a sealing ring being disposed outside of said housing with said printed circuit board being supported between said elastic hooks and said sealing ring to thereby cause deformation of said sealing ring.
