An electrical assembly includes a housing extending between front and rear ends. The housing includes a post extending between a base end and a free that is loaded into a passage of the circuit board and engages the circuit board in a primary locking operation such that the post secures the housing to the board by a primary holding force. A contact is received in the housing and has a mating end at the front end of the housing for mating with a mating electrical assembly and a terminating end at the rear end of the housing for electrical connection with the board. The free end of the post is locked to the rear side of the board by a secondary locking operation that secures the housing to the board by a secondary holding force that is greater than the primary holding force.
