Abstract
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.
