The Astro Switch is a gimmick from Mega Man 8, found in Astro Man's stage. It is a large button that can be activated by jumping on top of it.
Astro Switches are stationary buttons that can trigger any object by giving it a "myFlag" value in creation code identical to that of the object to trigger (though they are primarily intended to control Astro Doors). Mega Man can use them by simply jumping on top of one, where it will remain pressed down until he moves off of it.
- In all devkits Astro Switches have appeared in to date, they are named "objMM8Switch".
- Although a green Astro Switch sprite exists, the object lacks a "col" variable to set it like most objects with different palettes. A green Astro Switch must instead be set via typing "sprite_index = sprMM8ButtonG" in an Astro Door's creation code.
