ABSTRACT:
An electrical connector assembly includes two connectors (22, 24), wherein the first connector has a pair of contacts (46A, 46B, FIG. 9 ) which rapidly break engagement as the connectors slowly approach each other. An actuator (60), has a ridge deflector (72) for moving back a contact end portion (52A), the actuator being urged rearwardly (R) by a first spring (100). However, a pair of rearwardly bowed trigger springs (82) press against surfaces (96) to resist rearward (R) actuator movement. As the connectors progressively approach each other, the first spring (100) is progressively compressed, causing increasing deflection of the middles of the trigger springs (82), until resistance offered by the trigger springs suddenly decreases. The actuator then moves rapidly rearward, so its deflector (72) moves back the contact end portion (52A) to rapidly open the switch. The actuator is rapidly moved back by the now-compressed first spring (100).
