安全装置。[Scope of Claim for Utility Model Registration] (1) Two pushbutton switches are connected in series to a predetermined drive circuit in a mechanical device such as a press unit, and both switches are operated simultaneously by both hands of the worker. A safety device having a pair of electrodes connected to each of the push-button switches so as to be in contact with both hands of the operator when operating each of the push-button switches, and closed when electrical conduction occurs between the electrodes. A safety device characterized in that a contact detection switch is connected in series to the push button switch. (2) The safety device according to claim 1, wherein the electrode is provided on the key top of the push button switch. (3) The safety device according to claim 1, wherein the electrode is formed on the surface of the operation console around the push button switch. (4) The safety device according to claim 1, wherein the contact detection switch is a relay switch including a relay coil that is energized by conduction between the electrodes.
