Actuating device

摘要

An actuating device is proposed for an electric/electronic device within an in particular flame-proof housing. The electrical/electronic device includes an essentially linearly movable on/off lever. In order to provide such an actuating device being accessible on the exterior of the respective flameproof housing and allowing mechanical actuation of the respective on/off lever without adversely affecting the flameproof housing, the actuating device includes at least a rotatably mounted handle disposed on the outside of the housing and a shaft connected with it in a rotatably fixed manner, the shaft being guided into the housing interior and there being connected movably to the on/off lever by a transformation gear for transforming rotational motion into linear motion.
