1. An electrical connector for electrically and mechanically interfacing with the peripheral surface of a projecting button connector for a biopotential electrode having an enlarged head connected to said electrode by a shank of reduced cross section relative to said head, said electrical connector comprising:

  • a connector housing defining an enclosed inner chamber, said housing having an inner end and an outer end spaced from and opposite to said inner end, a housing top wall extending between said inner end and said outer end and a housing bottom wall spaced from said housing top wall and extending between said inner end and said outer end,first and second opposed, spring biased arms mounted on said connector housing within said inner chamber adjacent to the inner end of said connector housing, each of said arms having a free end section adjacent to the outer end of said connector housing which is movable toward and away from the free end section of the remaining arm, andan actuator mounted on said connector housing at the outer end there of which extends outwardly from said outer end and which includes an actuator section which engages and extends between the free end sections of said first and second spring biased arms, said actuator being mounted for movement relative to said connector housing toward and away from the inner end there of between a first position defining the outermost extent of actuator movement away from the inner end of said connector housing and a second position closer to said inner end of said connector housing than said first position wherein said actuator section contacts and moves the free end sections of said first and second spring biased arms apart,each of said first and second spring biased arms being biased toward the remaining arm with the free end sections thereof being biased toward engagement with said actuator section.
