This utility model discloses an indicator light switch mechanism for a transfer case hydraulic shifting mechanism, including a trigger switch mounted on the axial slide of the shift fork lever and a triggering part mounted on the shift fork lever. The trigger switch has a trigger element; the triggering part only pushes the trigger element of the trigger switch to close the trigger switch when the shift fork lever is pushed into position. When the shift fork lever retracts and disengages from a certain gear, the trigger switch opens. Its advantage is that the indicator light only illuminates after the shift fork shaft is fully pushed into position and the shift is truly successful. Compared with existing technologies that rely on pneumatic or hydraulic sensors to illuminate the indicator light before or ultimately unsuccessfully shifting gears, thus creating a false alarm, this mechanism avoids the operator continuing to perform invalid operations when the shift is unsuccessful.
