A sealed latch assembly for a vehicle closure panel is provided. The latch assembly includes a housing having an internal cavity sized for receipt of internal components of the latch assembly. A cover is attached to the housing to enclose at least a portion of the internal cavity. The latch assembly includes a sealing member and a deflector member that are brought into engagement to define a sealing interface. The sealing member contacts a side of the deflector member when assembled, and the sealing member is deflected to create a water-tight seal. The housing and the cover are secured by a snap fit arrangement with a low compressive load, as the deflector does not compress the seal member.
