Fix vertical alignment and value spacing of compact-mode switch buttons

[jimtng]

Before:

• The value appears to not be vertically centered against the button, especially against the labels inside the buttons)
• The value is too close to the buttons

After:

• Removed the top padding of the buttons, thus bringing them higher and centered against the value to its left
• Added some spacing between the value and the buttons

How it looks (after) with icons:

---

Before:
The value is too close to the on/off button

After:
Added some spacing between the value and the buttons
