Abstract: We investigate under which parameter regimes the MHD Rankine-Hugoniot conditions, which describe discontinuous solutions to the MHD equations, allow for switch-on and switch-off shock solutions. We derive limiting values which agree with the literature and show how we can visualize these limits in the parameter space spanned by Alfven Mach number and plasma beta. We show that the superposition of a switch-on and a switch-off shock is also an MHD shock, such that the magnetic field is aligned with the shock normal.
