<p>A shock sensor (300) comprises: a lead switch (310) fixed in the sensor case, and having a lead contact which changes from a first state to a second state by a magnetic force; a magnet (315) fixed apart from the lead switch by a given distance in the sensor case; a shielding member (317) having a sufficient area to shield the lead contact from the magnet force when the member is in the steady-state position; and resilient members (323) holding the shielding member in the steady-state position between the lead contact and the magnet when the sensor is in the steady state so as to hold the lead contact in the first state, and moving the member to a position so as to cause the lead contact to reach the second state when the sensor receives a shock.</p> |
