PURPOSE: A three-way passage switch valve for a boiler is provided to switch a passage by opening and closing selectively first and second discharge ports by moving up and down a valve member in a passage switch chamber according to power-supply of a solenoid assembly. CONSTITUTION: A three-way passage switch valve for a boiler is composed of a valve housing(10) having an inlet port(11), first and second discharge ports(12,13) facing each other, and a passage switch chamber(14) communicating with the inlet port and the first and second discharge ports; a valve member(20) disposed in the passage switch chamber of the valve housing to move rectilinearly and vertically and to communicate selectively the inlet port with one of the first and second discharge ports; an armature rod(30) connected rectilinearly with the valve member with penetrating the first discharge port arranged at the upside to drive the valve member and moved downward by self-weight; and a solenoid assembly(40) installed at the upper part of the valve housing to move upward the valve member together with the armature rod according to an electrical signal.
