<p>A shock sensor (100; 200; 300) comprising a casing defining a cylindrical space therein. The sensor includes a protecting tube (12) placed the cylindrical space so as to define an annular space between the casing and the protecting tube and having an inner space therein, and a partitioning member (14; 214; 310) provided in the inner space so as to extend in parallel to the longitudinal axis of the protecting tube and to divide the inner space into a plurality of compartments extending substantially parallel to the protecting tube. The sensor also includes a plurality of reed switches (15,15) positioned one in each of the compartments, and insulating members placed in remaining spaces in the compartments, and a magnetic actuating device (18) for actuating the reed switches when a shock of predetermined magnitude acts on the sensor. <IMAGE></p> |
