An initiator including a housing adapted to be received in an igniter or rocket motor, at least one charge at a distal end of the housing, an electro-explosive device behind the charge for detonating the charge when subject to a voltage HV, and a pressure bulkhead behind the electro-explosive device. An electronic subsystem in the housing is connected to the electro-explosive device through the bulkhead and includes a lead for providing the voltage HV to the electro-explosive device to initiate it, and a switch in the lead which does not conduct if errant voltages are present on the lead to prevent initiation of the electro-explosive device until the correct voltage HV is present.

Disclosed is a claymore mine on which a device for preventing a breakdown attributable to a power noise has been mounted. In order to prevent an electric primer from operating due to a power noise induced by a magnetic field or generated by the falling of a thunderbolt or other factors, such as a communication device, a shield layer formed by weaving or braiding a conductive fiber, such as a carbon fiber, or weaving or braiding a copper-plated tin wire, is formed in the wire and percussion unit of the claymore mine. In order to discharge a power noise introduced into the wire and the percussion unit to the earth, a power noise discharge adaptor including a plurality of diodes, a TVS, a GDT, and an SPD is formed. Accordingly, the introduction of a power noise can be fundamentally blocked, and a power noise can be safely discharged to the earth if the power noise is introduced.
