摘要： An electric safety switch apparatus of a type including an electric switch means and controllably movable switch-operating means for actuating the electric switch means between open and closed relationship with respect to an electric circuit adapted to be connected to the electric switch means and further including inactivating means effectively cooperable with respect to the switch-operating means with respect to the electric switch means for effectively preventing the actuation thereof by said switch-operating means when in any position other than a predetermined, switch-engaging, inactivating-means bypassing relationship thereof. The switch-operating means has an input portion, an output portion, and an intervening coupling portion, with said input portion including means adapted to be effectively manually moved to an extent such as to actuate said electric switch means when said switch-operating means is in said predetermined switch-engaging, inactivating-means-bypassing relationship. The apparatus includes means for properly positioning said switch-operating means for manually caused movement into said bypassing relationship when operated by authorized personnel in accordance with a preselected, positiondetermining manner by said means.
