TX Cnc is a member of the young open cluster NGC 2632. In the present paper,four CCD epochs of light minimum and a complete V light curve of TX Cnc arepresented. A period investigation based on all available photoelectric or CCDdata showed that it is found to be superimposed on a long-term increase($dP/dt=+3.97\times{10^{-8}}$\,days/year), and a weak evidence suggests that itincludes a small-amplitude period oscillation ($A_3=0.^{d}0028$;$T_3=26.6\,years$). The light curves in the V band obtained in 2004 wereanalyzed with the 2003 version of the W-D code. It was shown that TX Cnc is anovercontact binary system with a degree of contact factor $f=24.8%(\pm0.9%)$.The absolute parameters of the system were calculated:$M_1=1.319\pm0.007M_{\odot}$, $M_2=0.600\pm0.01M_{\odot}$;$R_1=1.28\pm0.19R_{\odot}$, $R_2=0.91\pm0.13R_{\odot}$. TX Cnc may be on theTRO-controlled stage of the evolutionary scheme proposed by Qian (2001a, b;2003a), and may contains an invisible tertiary component($m_3\approx0.097M_{\odot}$). If this is true, the tertiary component hasplayed an important role in the formation and evolution of TX Cnc by removingangular momentum from the central system(Pribulla & Rucinski, 2006). In thisway the contact binary configuration can be formed in the short life time of ayoung open cluster via AML.
