The multi-color passband CCD light curves of ASAS J124343+1531.7 and LINEAR2323566 were first obtained by the 0.84-m Ritchey-Chr\'{e}tien telescope withfollow up observations by the WIYN 0.90m Cassegrain telescope. The data fromthe $Transiting\quad Exoplanet\quad Survey\quad Satellite\quad (TESS)$ of ASASJ124343+1531.7 was also applied for subsequent analysis. By analyzing the datathrough the W-D program, their mass ratios and fill-out factors were determinedas 3.758, 1.438 and 31.8$\%$, 14.9$\%$, respectively. ASAS J124343+1531.7 is aW-subtype median contact binary, while LINEAR 2323566 is a W-subtype shallowcontact binary, and the asymmetric light curves prove that they both have theO'Connell effect, which is generally explained by magnetic activity. Theequivalent widths (EWs) of H$_\alpha$ lines were calculated, which show theycertainly have magnetic activity. Moreover, LINEAR 2323566 has a strongermagnetic activity. The analysis of orbital period changes shows that ASASJ124343+1531.7 has a trend of secular period increase, which is generallyexplained by the mass transfer from the less massive to the more massive star.According to the estimated absolute parameters, their evolutionary states arediscussed. The two components of ASAS J124343+1531.7 are both main sequencestars. 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 andover-sized.

The first photometric investigation and spectroscopic analysis of two contact binaries: ASAS J124343+1531.7 and LINEAR 2323566
