Abstract
A door lock apparatus with safety switch capable of locking a door. A coupling member is pivotally moved about a pivotal shaft by a closing operation by 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 door. Whether the door is of a slide or pivot type, the door is assuredly locked in a closed state because the door is inhibited from moving in the two directions including the moving direction thereof. If an operation mistake is made to open the door, the force for opening the door is not directly applied to the switch body or the actuator. A safety switch may achieve an increase in durability.
