Prof Google isn't helpful. I gather it's some sort of igniter.
The
S-211 Flight Manual (details earlier for FREE download) may have more info however these two GIFs give most of the SEARing info for MB10 ejection seat with canopy breaker horns for occupants to eject through the canopy. The MB326H seat was a Mk.4 Martin-Baker with canopy breakers on the top of the seat in case the canopy did not separate. Then an interesting TIDBIT about the canopy
ON THE GROUND when it cannot be opened. Heaven Forfend. Early MB326Hs did not have the CANOPY BREAKER TOOL wot was developed when a fatal crash caused by -
canopy opening in flight - gave a wake up call about side opening freakin' canopies. [Also the canopy lock lever was redesigned.]
