<p>PROBLEM TO BE SOLVED: To provide an inexpensive electric firing triggering device having at least one electric receptacle for inspecting a resistive heating element forming the triggering device in a short time without increasing the size. SOLUTION: The electric firing triggering device has two firing head sections 16, 17 each comprising a thermal reaction powder and a resistive heating element. Two resistive heating elements are built in an electric circuit having three electric joints 3, 4, 5 one of which is common to both resistive heating elements and two other electric joints are connected, respectively, with two resistive heating elements. Three electric joints are connected with a power supply means from a controller.</p> |
