摘要： A safety switch is improved by the feature of staying in an open position in the event of breakage of a working rod or breakage or dropout of an operation portion and having a simple structure facilitating size reduction. Even if a rotary shaft is released from a supported state in an operation portion because an operating force of an operation or the number of operations of extracting an actuator from the operation portion exceeds a breakage tolerance, a working rod is permitted to move in an urging direction of a coil spring and is assuredly moved to the operation portion. Therefore, a switch can be assuredly set to an open position and, hence, the safety switch can achieve the safety improvement.
摘要翻译：通过在工作棒断裂或操作部分断裂或脱落的情况下保持在打开位置并且具有便于尺寸减小的简单结构的特征来改进安全开关。即使旋转轴从操作部的支撑状态被释放，因为操作的操作力或从操作部提取致动器的操作次数超过了断裂公差，所以允许工作杆以推动力移动螺旋弹簧的方向被确定地移动到操作部。因此，可以将开关确定地设定为打开位置，因此安全开关可以实现安全性的改善。

摘要： A safety switch is provided which is increased in durability and which offers a high degree of freedom of mounting the safety switch to place.A switch body has a rectangular solid shape. An actuator entrance hole is formed at one of the opposite corner portions of the switch body whereas a cable lead-out port is formed at the other corner portion, whereby the safety switch is increased in the degree of mounting freedom. Thus is offered a wider choice of place to mount the safety switch. The switch body is formed with only one actuator entrance hole so that the safety switch is prevented from suffering failure caused by foreign substances invading through an actuator entrance hole left unused. In addition, a driving cam may be formed with an engaging portion and a cam curve portion in spaced relation so that the driving cam is configured to be free from an area having poor strength. Thus, the driving cam is increased in strength. This leads to the increased durability of the safety switch.
摘要翻译：提供了一种安全开关，其增加了耐用性，并且提供了将安全开关安装到位的高度自由度。开关体具有矩形的实心形状。致动器入口孔形成在开关体的相对的拐角部分的一个处，而在另一个拐角处形成电缆引出口，由此安全开关的安装自由度增加。因此，可以提供更多选择安装安全开关的位置。开关体仅形成有一个致动器入口孔，从而防止安全开关因留下未使用的致动器入口侵入的异物而引起故障。此外，驱动凸轮可以形成有间隔开的接合部分和凸轮曲线部分，使得驱动凸轮被构造成不具有较差强度的区域。因此，驱动凸轮的强度增加。这导致安全开关的耐久性提高。

摘要： 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.

摘要： A safety switch is described in which a switching contact in a lock mechanism switches between an open and closed condition. Switching is coupled to a lock member moveable between a locked position, locking a drive cam, and an unlocked position, allowing the cam to rotate. A link member, cooperating with the lock member, switches between open and closed conditions of normally-open and normally-closed switching contacts, indicating movement of the lock member between the locked position and the unlocked position. By monitoring the open and closed conditions of the normally-open and normally-closed switching contacts, it is possible to determine the state of the lock member, i.e., whether it is in the locked position or in the unlocked position. It therefore can be determined whether the drive cam is in the locked or unlocked (i.e., free to rotate) state.

摘要： A safety switch capable of detecting withdrawal of an actuator from a switch main unit in a sure and reliable manner even when the safely switch, including a lock mechanism, is in a locked condition and an attempt is made to forcibly withdraw the actuator from the switch main unit. Even when a drive cam becomes capable of rotation since not less than one of a notch cut-out section and a lock member is broken by forcibly extracting an actuator with rotation of the drive cam locked, a cam curve section of the drive cam and an operating rod are in a normal condition and free of breakage. Accordingly, if the drive cam rotates in a counter-clockwise direction, normally-closed contacts of a contact section adopt an open condition normally, and even in situations where the actuator is withdrawn from the switch main unit with a force equal to or greater than the fracture strength of the safety switch, withdrawal of the actuator from the switch main unit can be detected in a sure and reliable manner.
摘要翻译：一种安全开关，即使在包括锁定机构的安全开关处于锁定状态并且试图强制地从开关中撤出致动器的情况下，能够以可靠的方式检测致动器从开关主单元的拔出主机即使当驱动凸轮变得能够旋转时，由于通过驱动凸轮被锁定的旋转强制地抽出致动器，因此在凹口切口部和锁定部件中的一个不小于其中一个，驱动凸轮的凸轮曲线部分和操作杆处于正常状态，无破损。因此，如果驱动凸轮沿逆时针方向旋转，则接触部的常闭触点通常采用打开状态，并且即使在致动器从开关主单元以等于或大于安全开关的断裂强度，致动器从开关主机的取出可以确定可靠地检测。

摘要： A safety switch is provided in which the open-close condition of a switching contact provided in a lock mechanism is reliably switched in a manner coupled with a motion of a lock member between a lock position and a unlock position. Since a link member, which directly and simultaneously switches the open-close conditions of normally-open and normally-closed switching contacts pursuant to the motion of a lock member, is provided, the open-close conditions of the normally-open and normally-close switching contacts can be switched reliably in a coupled manner with the motion of the lock member between the lock position and the unlock position. As a result, for example, by monitoring the open-close conditions of the normally-open and normally-close switching contacts, it is possible to determine to which of the lock position and the unlock position the lock member has moved, that is, which of the locked state and the unlocked state the rotation of the drive cam is in.
