ABSTRACT:
A shock sensor capable of detecting a shock in a number of directions includes a reed switch, which is fixed inside a body and has a reed contact part which is magnetically changed from a first to a second state by way of a magnet, which is fixed inside the body at a specified distance from the reed switch. A shield member, having a sufficiently large area, prevents the magnet force of the magnet from affecting the reed contact part when the shield member is in its regular position. A resilient member, in a normal state, keeps the shield member at its regular position between the reed contact part and a magnet, at which the reed contact part is kept in the first state. When a shock is applied to the shock sensor, the resilient member allows the shield member to move to a position where the reed contact part changes over to the second state.
In a second embodiment, the magnet is movably held in the main casing at a specified distance from the reed switch. In a normal state, the position of the magnet is such that a magnetism does not affect the reed contact part. When a shock is applied to the shock sensor, the magnet moves to a second position where the reed contact part is changed over to the second state.
