ABSTRACT:
In an electrical circuit arrangement, specifically a sequential blasting system as used in mining, the individual circuit units 12 are contacted by a continuous flat cable 10 in such a way that each wire 16 to 19 of the cable 10 has a bared section 21 which is soldered to a contact pad 22 to 26 of a conductor pattern 15 disposed on a printed circuit board 11 which carries the circuit elements of the circuit unit 12. This not only minimizes the total number of contacts but also prevents the contact points from increasing the line resistance and prevents any faulty contact point from interrupting the line.
