Sectioned M26

After seeing this pic on one site, I commenced to looking for who did the work/posted the photo.

Ran across this:http://www.reddit.com/r/pics/comments/1jyt73/inside_of_a_frag_grenade/

Some other links of interest there, as well.

anyone got a good explanation on how this fuse works? it still baffles me.:tinysmile_grin_t:

Extracts from documents i have
"Hand grenade M26A2 is assembled with an electrical impact fuze M217 which incorporates a secondary pyrotechnic delay feature which detonates the grenade if it fails to detonate upon impact,"
"Fuze m217 is equipped with a safety pin,the split end of which is either spread or has a diamond crimp, and pull ring,IMPACT is embossed on the safety lever (older models had red safety levers with or without impact painted theron in black)
The major components are as follows:
A Bouchon assembly,
a fuze body assembly (which incorporates a thermal power supply,an arming delay thermal switch,a delay detonation terminal switch assembly,an impact switch assembly and an electrical detonator)
and a booster pellet



"Functioning;
Removal of safety pin permits release of the safety lever,
when the grenade is thrown the striker assembly.through action of the striker pin thows off the safety lever and impacts the percussion primer.
The primer initiates the power supply,which causes the fuze to arm within 1 to 2 seconds,there after the grenade is subject to detonation upon impact.
If the grenade does not detonate on impact (after proper arming time) the grenade will be detonated by the secondary pyrotechnic delay feature.
If the fuze fails to function after release of the safety lever ,the fuze power supply will become inactive within 30 seconds"

The cutaway grenade in the first post is actually an experimental model with a T1018 fuze mechanism. It was a time delay fuze with a selective Impact element. The idea being you could choose impact or time. Development began in june 1952 and was terminated in November 1958.

It's T designation according to AMCP 706-240 is the T1012 fuze which became the m-217 no? they look quite similar unless the manual is wrong?
