Switchbacks are Aflv\'enic fluctuations in the solar wind, which exhibitlarge rotations in the magnetic field direction. Observations from Parker SolarProbe's (PSP's) first two solar encounters have formed the basis for many ofthe described switchback properties and generation mechanisms. However, thisearly data may not be representative of the typical near-Sun solar wind,biasing our current understanding of these phenomena. One defining switchbackproperty is the magnetic deflection direction. During the first solarencounter, this was primarily in the tangential direction for the longestswitchbacks, which has since been discussed as evidence, and a testableprediction, of several switchback generation methods. In this study, were-examine the deflection direction of switchbacks during the first eight PSPencounters to confirm the existence of a systematic deflection direction. Wefirst identify switchbacks exceeding a threshold deflection in the magneticfield and confirm a previous finding that they are arc-polarized. In agreementwith earlier results from PSP's first encounter, we find that groups of longerswitchbacks tend to deflect in the same direction for several hours. However,in contrast to earlier studies, we find that there is no unique direction forthese deflections, although several solar encounters showed a non-uniformdistribution in deflection direction with a slight preference for thetangential direction. This result suggests a systematic magnetic configurationfor switchback generation, which is consistent with interchange reconnection asa source mechanism, although this new evidence does not rule out othermechanisms, such as the expansion of wave modes.
