  The multi-color passband CCD light curves of ASAS J124343+1531.7 and LINEAR
2323566 were first obtained by the 0.84-m Ritchey-Chr\'{e}tien telescope with
follow up observations by the WIYN 0.90m Cassegrain telescope. The data from
the $Transiting\quad Exoplanet\quad Survey\quad Satellite\quad (TESS)$ of ASAS
J124343+1531.7 was also applied for subsequent analysis. By analyzing the data
through the W-D program, their mass ratios and fill-out factors were determined
as 3.758, 1.438 and 31.8$\%$, 14.9$\%$, respectively. ASAS J124343+1531.7 is a
W-subtype median contact binary, while LINEAR 2323566 is a W-subtype shallow
contact binary, and the asymmetric light curves prove that they both have the
O'Connell effect, which is generally explained by magnetic activity. The
equivalent widths (EWs) of H$_\alpha$ lines were calculated, which show they
certainly have magnetic activity. Moreover, LINEAR 2323566 has a stronger
magnetic activity. The analysis of orbital period changes shows that ASAS
J124343+1531.7 has a trend of secular period increase, which is generally
explained by the mass transfer from the less massive to the more massive star.
According to the estimated absolute parameters, their evolutionary states are
discussed. The two components of ASAS J124343+1531.7 are both main sequence
stars. While for LINEAR 2323566, the more massive star is a main sequence star,
the less massive star has evolved out of main sequence and is over-luminous and
over-sized.
