My first guess was possibly a variation on the French F series ( similar to F-2) firing device used with Claymore type mines, but not sure now. I could be way off. It takes 1 D cell battery, instead of 2 on F-2, also different input/output arrangement. Any info would be appreciated.

Electronic Fuze Identification, possibly a French?
It is called the 'TEST UNIT' or 'CONTROL UNIT' in english.
The control unit consists of two main components and is used remotely to check that the circuit is correct. The unit comprises a battery container, which
accepts a battery type LR20 (NBA3030 in French military nomenclature) and a body which contains the electronic circuitry. These two components screw together and the joint is sealed by use of an O ring. The following components are situated on the top of the body :
1 A two pin plug which mates with one of the twin pole sockets on the safety and control line Tee connector.
2 A test lamp which lights when the fuze circuitry and power supplies are correct.
3 A test button which enables the state of the control unit to be verified
Cheers,
