Please help me identify this WW2 British fuze(?) tin

[zapper]

This tin just arrived together with a lot of WW2 sabotage- and demolition equipment.
Unfortunately it didn't come with a lid. It has a manufacturer marking and broad arrow embossed.
I would appreciate if someone could shed some light on what kind of fuze/switch this tin was intended for.
