The phrase means, "lets fight". It is calling a person out for a physical confrontation.

This phrase was not originated, coined, or started by Vybz Kartel. Vybz Kartel remade Bingie General's song "Touch A Button Nuh". General Bingie took the beat for "Touch A Button Nuh" from Sugar Ray's song "Bubblin' Pot"

The phrase may have deeper roots than that.
Why you looking at me crossed? You vexing me. Touch a button now.
