A press and spring-back terminal block, includes a housing (1), a conductive terminal (2), a retainer assembly (3) and a rocker (4). The conductive terminal (2) is arranged inside the housing (1). The retainer assembly (3) includes a control member (30) and an elastic sheet (31) actuated by the control member (30). The elastic sheet (31) includes a stopping edge (310) and a retaining end (311) extended from the stopping edge (310) and toward the conductive terminal (2). When the control member (30) is actuated, it is abutted by the stopping edge (310) to allow the retaining end (311) to swing toward one side away from the conductive terminal (2). The rocker (4) is arranged inside the housing (1) and includes a first end portion (41) opposite from the lead wire insertion hole (11) and a second end portion driven to move relative to the control member (30).
