A switchblade is an automatic open knife. You only have to press a button and the blade deploys. These are illegal to own in many states and illegal to carry in public in others. A spring loaded knife is an assisted open blade. This means that you still have to apply some pressure to get it to open, either with a thub stud or with a flipper. These are legal in most places, depending on the length of the blade. There are various assisted opening mechanisms and spring loaded is one of them. Others include ones operated by torsion bars like Ken Onion SpeedSafe, which is used in Kershaw and Zero Tolerance knives

switchblade (spring loaded knives)
Yes they are
A real switchblade knife uses a spring loaded blade hidden inside the hollow handle and a release lever. When the release lever (i.e. switch) is flipped the spring rapidly forces the blade from the hollow handle into position for use and the blade latches on a catch that is part of the release lever. To put the blade back in the hollow handle the release lever is moved to unlatch the catch and the tip of the blade is pressed against a hard surface to compress the spring again. The image shows one of these switchblade knives with the release lever clearly visible.

Friction batons require manual extension by pulling them out, while spring-loaded batons use a spring mechanism for automatic extension with the push of a button. Friction batons are more prone to user error and may require more force to extend, while spring-loaded batons offer quicker deployment and can be easier to handle in high-pressure situations.

Take a pushrod and push down on the plunger in the lifter. A hydraulic lifter is spring loaded.
Only if you are in the Military can you carry ANY type of switchblade. Now, "spring assisted" you can carry (its a "switchblade" if you can push a button on the handle to automatically release the blade).
