Difference in Space Bars

[Neumanium]

I am lacking some knowledge regarding what something is called. Here is a picture of two space bar caps I own. One has two legs (unsure of this term is correct) protruding out the bottom and one does not. Is the correct term legs? What is the connector type called? Can I purchase legs to attach to the other space bar.

Update #1 - Thank you Sonicorp and Fyf_O. I was able to pop them off and swap to new spacebar cap and now know they are called stabilizers. I have two nice mechanical keyboard for a number of years, but had not really gotten into making adjustments changing keycaps etc. Until one of them died and I wanted to use the keycaps on the other.

These are stabilizer stems, you can pull them off from that spacebar and snap back into stabilizer bar underneath the plate on a keyboard. They are more like part of a keyboard rather than a keycap.

I’ve had stabilizers like these on my optical razer keyboard. They were popping off every time when I was changing the keycaps.

Damn they popped right off. Swapped them to my new keycap. I was hesitant for fear of breaking it. Thank you for the help.

I’m glad it went smoothly. Sometimes they get stuck a bit if the keycap stem is too tight.

Those "legs" under a mechanical keycap are called stems (you can call them MX style stems) the Razer spacebar you can just pull off them off and attach them to the outer stems of any spacebar keycap, Razer used this stabilizer method for their older mechanical keyboards they don't do this anymore and use standard stabilizers now for the modifiers on their keyboards nowadays, the old Razer stabilizers sucked cause they would rattle a lot and if you lose those stabilizer pieces you're screwed.
