ABSTRACT OF THE DISCLOSURE A shock and vibration sensitive switch for detecting the presence of an intruder comprises two E-shaped electrodes mounted on opposite sides of a cavity. Two inertia weights are supported by the electrodes and are in an electrical parallel arrangement, whereby the inertia weights provide redundant current paths allowing proper switch operation in the event of failure of one of said current paths. The switch is hermetically sealed to prevent moisture and the contaminants outgassed by the switch lead wires from entering the interior of the switch.
