Electronically controllable deadbolt

i'm working on parachute ejection system, here:


my device controlled arduino nano.

now i'm looking release hatch. don't want use servo, because, know, servos always draw power. i'm looking alternative mechanical part.

in everyday language i'd say: electronically controllable deadbolt

something here electromagnet or electromotor or ...



but have no idea how such thing called - can not google it.

if use servo.detach() arduino stops sending regular pulse hold in position, @ time i'm pretty sure motor draw negligible if current since it's not trying keep position.

if servo not being loaded, ie there's no force trying move it, servo attached there's little if current.

searching "solenoid" might help, or "solenoid deadbolt" or similar?
