I prefer twist wires.
Twist & tape is easy and reliable. I also like PCB screw switches. Missile Works has a few to choose from but there are many more out there.

I usually use these: https://doghouse.blastzone.org/switches.html
Lots use T and T. I'd check with a TAP/L3CC if attempting with an L3 project. Some might frown down upon it. Kurt Savegnago
This is always true.

I have a 2.5" that uses that switch. It's very nice, but bulky on those smaller tubes. 3"+ tubing, those are awesome. I started using lever switches with pull pins guided by a small piece of launch lug. Works extremely reliably. Plus I love having my red "Remove Before Flight" tags on the pull pin.
Egg Timer Rocketry has a coded remote switch and now a Wi-fi switch one can turn on via B/T from a portable device. https://www.eggtimerrocketry.com/page55.php
It's so new the documentation or FAQ isn't up yet. I'm springing for a couple. Kurt Savegnago

That's a very good safety maneuver!!!! Helps avoid ballistic launches if one gets outta sync. (ie. put igniter in before turning things on.) Kurt

That switch fits in a 38mm ebay, as shown here in my LOC Weasel clone. No problemo.

I like the simplicity, reliability and versatility of screw switches. I usually mount them so that I can reach them through an existing vent hole. I've standardized on the ones made by Missile Works:

Buy these (in bulk) https://www.digikey.com/product-detail/en/50212LX/SC1821-ND/1642037
Epoxy over the crimp tabs and they are golden.
Use one to disconnect and shunt all four pyro's with one switch.
Use a second switch for four sets of power contacts for the quad-pyro [MARSA54] altimeter.
Flown 100's of times without issue....

x2 on this! I use missileworks screw switches in everything. I replace the screw with a button head hex screw. with a ball end hex wrench you can reach two switches thru one hole.
38mm, I trimmed the switch a little
54mm
3"
4"
