    摘要： A security system, for use with a chassis enclosing electrical circuitry and having a lid movable relative to the chassis to allow access to the electrical circuitry, including: (1) a plurality of switches, couplable to the electrical circuitry, that are configured to store a security code readable by the electrical circuitry and (2) a trip mechanism, coupled to the chassis, that alters the security code stored by the plurality of switches when the lid is moved relative to the chassis, whereby the electrical circuitry may detect that the lid has been moved by detecting that the security code has been altered.
