Abstract

The present invention relates to a signalling module (100) for a medicament delivery device (10), the medicament delivery device comprising a power pack (42), in turn comprising a drive spring (44) operably connected to a plunger rod (46), the plunger rod arranged to, when the power pack is activated, act on a syringe (36) for delivering a dose of medicament, the signalling module (100) comprising: a signalling element (102; 110) comprising at least one biased force element (106; 114) operably connected to said plunger rod; an impact surface (44; 56); the signalling element (102; 110) being held in a tensioned state by the plunger rod (46) in an initial state, wherein, when the power pack (42) is activated, causes a linear movement of the plunger rod (46) in a proximal direction, thereby releasing the signalling element (102; 110) at a position close to end of dose delivery, wherein said signalling element hits said impact surface (44; 56) and causes an indication to a user that a dose of medicament has been delivered.
