Hi and welcome. Most of those-- they're usually called a "Kicker Chip" or a "Kick"-- just drop into the tube and the battery makes contact through them. Looking at your photo, it seems there are side contacts to touch the tube, but not one to contact the battery, so I am not sure. You got no documentation? Can you give me a brand name, or something else to look for? Meching is a lot of fun-- I'm a mekkie from way back, just got a new one today-- but it can be dangerous if you aren't careful. Tell me some more about your rig
