What ₛ means
Its role depends on the phonetic notation. ₛ is a distinct subscript sign, not a universal symbol for one sound. The notation key or surrounding letters tell you what it marks.
The Uralic Phonetic Alphabet, a system for writing sounds in Uralic languages, used ₛ before its formal standardization in 1902. A 1972 source on Quebec French phonetics used subscript s for fricative release—the friction heard as a consonant is released.
Specialist notation; its reading depends on the transcription system.
Without the notation key, do not infer one universal sound value.

1Can I use ₛ as a regular subscript in an equation?
Usually no. Use your editor’s subscript formatting for ordinary equations or styled text; ₛ is its own character and belongs where a notation specifically calls for it.
