Finger operated button activating wireless transmission path for effecting voluntary release of a ski binding

In a ski binding comprising a means for effecting a voluntary release of a lock mechanism on a jaw of a safety ski binding through a wireless transmission path, a switch means for operably controlling signal information in said wireless transmission path, said switch means including a manually operable button arranged on a base means separate from said safety ski binding and used in conjunction with said safety ski binding, the improvement wherein an outwardly opening recess means is provided on said base means, said button being located in said recess means so that a part thereof adapted to be manually engaged is oriented beneath an imaginary extension of the outer surface of said base means so as to protect said button from an unintentional manual engagement, support means on said base means for supporting the entirety of said button for movement in the same direction relative to said base means, said recess means including surrounding wall means of finite dimensions defining a surface opening and a depth dimension to said button that is at least one of equal to and greater than a maximum width dimension for said surface opening, said surface opening having a cross sectional area sufficient to limit the reception of only one human finger into said surface opening, said depth dimension being sufficient to require a longitudinal axis of the finger to be generally aligned with a longitudinal axis of said recess means to enable the finger to be received into said recess means and to manually operate said button to cause said switch means to allow a transmission of signal information in said wireless transmission path to facilitate a release of said lock mechanism on a jaw of said safety ski binding.
