Switch

A Switch is a power exchange (also known as kink or BDSM) practitioner whose sexual preference, identity, or orientation may involve either taking on the role of Dominant, where they control the dynamic, or as a submissive, where they are giving up some or all control. (1)

This type of dynamic is versatile and has no specific rules or boundaries. It is quite common that a switch can be solely one orientation with one person in a D/s relationship and a switch with others. (2)
