PROBLEM TO BE SOLVED: To provide a vehicular warning switch device capable of reliably detecting fitting failure of a connector by changing a simple warning switch structure. SOLUTION: In a vehicular warning switch device having a liquid level warning switch 5 turned on by a drop in a brake fluid level, a brake warning lamp 29 connected in series to the liquid level warning switch 5 via a connector 30 and actuated by ON operation of the liquid level warning switch 5 and a fail-safe circuit having an input terminal 33 and performing prescribed fail-safe processing when the liquid level warning switch 5 is turned on, the vehicular warning switch device is formed as a means for setting a connecting point 35 of warning lamp lines (31a), 31b for connecting the liquid level warning switch 5 and the brake warning lamp 29 and branch lines 32a, 32b to the liquid level warning switch 5 side close to the connector 30.
