    摘要： The present disclosure relates to a blind rivet fastener (1) for an electrical contact assembly, including a rivet shaft comprising an elongated, hollow sleeve extending coaxially to a longitudinal centre axis of the blind rivet fastener (1) and having an outer sleeve surface and a rivet head (13) extending radially at a first end of the sleeve; wherein the rivet shaft comprises at least one ridge (14) configured to scratch at least one component (103; 104), wherein the at least one ridge (14) projects from the rivet head (13) and extends along a portion of the outer sleeve surface. The disclosure also relates to a fastening arrangement (100') comprising such a blind rivet fastener (1).

    摘要： An indicator assembly for determining a liquid level condition (15) within a tank (12) includes a dial assembly (28) and a removable sensor module (30) connected to the dial assembly (28). The dial assembly has a base (60) and a cover (64) connected to the base. A channel (48) formed in the cover has a go-no-go protrusion (158, 160). An actuator (50) is movable in response to a change in liquid level. The sensor module (30) is shaped for insertion into the channel (48) and has a housing (170) with a sensor (58) for determining movement of the actuator. A go-no-go cavity (162, 164) complementary in shape with the go-no-go protrusion (158, 160) is formed in the housing (170) permitting full insertion of the sensor module (30) into the channel (48) with the sensor (58) aligned with the actuator (50) for generating signals related to the liquid level condition.
