you're doing it all wrong, here's what you should do
- use one probe to firmly hold nickel strip against battery
- press second probe nearby
- watch for spark and burn marks, then pull probe away
- so: your hand is the switch, no fragile semiconductors need be sacrificed

if you think you need precise timing, you'd be so very wrong
besides, the cap discharge curve will act as a timer
even tho it's not needed
