ABSTRACT:
An electric ignition device having a pyrotechnical delay portion and a pyrotechnical ignition portion enclosed in a container. A first conducting ignition element is supported adjacent the delay portion and a second conducting ignition element is supported adjacent the ignition portion. The elements are connected in series to receive a voltage input from an external source. The first element is dimensioned so that it will heat to an ignition temperature in response to a particular low voltage level and will conduct when a higher second voltage level is applied. The second element will heat to an ignition temperature only when the second voltage level is applied. If the first voltage level is applied, the first element heats and ignites the delay portion and the delay portion burns at a particular rate for a characteristic delay interval and then ignites the ignition portion. If the second voltage is applied, the second element heats to rapidly ignite the ignition portion.
