摘要	The first complete VRcIc light curves of V608 Cas are presented and analyzed by using the 2010 version of the W-D code. The photometric results show that V608 Cas is a moderate mass-ratio (q = 0.373 +/- 0.005), shallow contact (f = 19.7 +/- 4.9%) binary. A cool spot is present on the massive component. The orbital period of V608 Cas may increase continuously according to the (0 - C) diagram, with a rate of dP/dt = +6.49 x 10(-7) days/year. The fundamental parameters of V608 Cas are estimated as: M-1 = 0.95 +/- 0.15M(circle dot), M-2 = 035 +/- 0.08M(circle dot), R-1 = 0.78 +/- 0.12R(circle dot), R-2 = 0.50 +/- 0.10R(circle dot), L-1 = 0.563 +/- 0.112L(circle dot), L-2 = 0.233 +/- 0.086L(circle dot), where the uncertainties mainly come from the uncertainty of the primary's effective temperature.
