Radial velocity measurements and simple sine-curve fits to the orbital velocity variations are presented for the second set of 10 contact binary systems. Eight systems are of the A type: AH Aur, CK Boo, DK Cyg, UZ Leo, XZ Leo, V839 Oph, GR Vir, and NN Vir; V842 Her is the only W type, while SV Equ appears to be a semidetached system seen at a low orbital inclination rather than a contact binary. Several of the studied systems are prime candidates for complete light and radial velocity synthesis solutions.
