Abstract
The invention concerns an igniter plug for a pyrotechnic device, in particular a hand-launch or mechanical launch grenade, comprising a body (104) provided with a control mechanism including a fly-off lever (101) and a percussion mechanism (128) co-operating with a primary pyrotechnic module (105) for initiating the charge (119) of the associated device. The invention is characterised in that it further comprises a lock (150) engaged with the lever (101), in storage position, to prevent the fly-off lever (101) from moving towards its release position, the lock (150) being configured to impose, when the igniter plug is activated, an initial movement of the lever (101) countering its displacement required for releasing the percussion mechanism (128), so as to disengage the lock (150) and the fly-off lever (101).
