Inert Pressure Pad Switch

The X-ray correct, inert pressure pad firing circuit will function via pressure. The circuit board contains all of the necessary components of an improvised explosive device (IED). The circuit is fully functional and will demonstrate that the firing switch has been activated by illuminating the LED in the blasting cap. The circuit board contains an X-ray correct battery, wire, switch, detonator, and inert pyrotechnic simulant.

Powered by four AA batteries, this IED circuit would be activated by applying pressure to the pressure pad switch. The X-ray correct thermite pyrotechnic simulant is engineered to have the same density and effective atomic number (Zeff) as the real explosive threat. Unlike most explosives, thermite displays blue in most material discrimination X-ray systems.
