To reduce the number of connecting lines to the triggering circuit, the number of current lead-in terminals (20, 21) multiplied by the number of lead-off or return terminals (22, 23) from the firing circuits corresponds at least to the number of trigger restraint circuits (14-17) which are provided;
To reduce the number of connecting lines to the triggering circuit, the number of current lead-in terminals (20, 21) multiplied by the number of lead-off or return terminals (22, 23) from the firing circuits corresponds at least to the number of trigger restraint circuits (14-17) which are provided; and each of the trigger circuits (14-17) is connected to a different combination of current lead-in terminals (20, 21) and current lead-off terminals (22, 23), for example: 14: 21, 22; 15: 21, 23; 16: 20, 22; 17: 20, 23. The firing circuits can be tested by a simple test unit (FIG. 2) in which, sequentially, different connection patterns to the current lead-in and lead-off terminals are provided, and current flow checked under standard test voltage conditions.
