The bright soliton solutions of the mixed 2-coupled nonlinear Schr{\"o}dinger (CNLS) equations with linear self and cross coupling terms have been obtained by identifying a transformation that transforms the corresponding equation to the integrable mixed 2-CNLS equations. The study on the collision dynamics of bright solitons shows that there exists periodic energy switching, due to the coupling terms. This periodic energy switching can be controlled by the new type of shape changing collisions of bright solitons arising in mixed 2-CNLS system, characterized by intensity redistribution, amplitude dependent phase shift and relative separation distance. We also point out that this system exhibits large periodic intensity switching even with very small linear self coupling strengths.
