In addition, coercive rotation preventing features such as gears, twists and torque shares will prove to be very useful for all type of door locks such as deadlocks, cylinder or lever-type knobs as they provide three to fivefold stronger safety.

Abstract: A door lock apparatus with safety switch capable of assuredly locking a door is provided. A coupling member is pivotally moved about a pivotal shaft by a closing operation by way of a rotary handle, thereby bringing an engaging portion thereof into engagement with a fixing member, so that a protective door is inhibited from moving in two directions of arrows X, Y including a moving direction of the protective door. Whether the protective door is of a slide type or a pivot type, the protective door is assuredly locked in a closed state because the protective door is inhibited from moving in the two directions including the moving direction thereof. Further, if an operation mistake or the like is made to forcibly open the protective door, the force for opening the protective door is not directly applied to the switch body or the actuator. Hence, a safety switch may achieve an increased in durability.
