Speed Brakes vs Spoilers: What's the Difference?

[@DavidBines]

Spoilers assist the ailerons. Speedbrake mode is commanded thru the handle on the left side of the pedestal on Boeing commercial jets. Upon closing the squat switch circuit the ground spoilers deploy. In air mode only the flight spoilers deploy whether thru turning the yoke or commanded thru the spoiler handle. The ratio changer and spoiler mixer determine the angle of rise in the applicable flight spoilers. The 737 Max aircraft have eliminated all the associated cables, ratio changer and mixer that all previous generation 737 utilized.

This video didn't have clear images to show the viewer where the speed brake and where the spoiler was on the plane. The stock videos weren't much help.
