Abstract
An electro-explosive initiator which may be either a coaxial or floating case type, for example, and which is constructed to be immune from the effects of electrostatic discharges. The initiator includes a bridgewire and contact pins for carrying an electric igniting signal to the bridgewire. The initiator has a discrete capacitor connected across the contact pins to shunt out the energy resulting from an electrostatic discharge pulse, and for preventing such energy from reaching the bridgewire.
