A safety switch input diagnosis device includes a circuit formed from a series connection of an emergency stop switch and a line having a resistor, a circuit connected at one end to one end of the circuit, a line connected at one end to another end of the circuit and at another end to a power supply, a line connected at one end to the other end of the circuit, a circuit connected at one end to the other end of the line and at another end to a ground, a circuit connected in parallel to the circuit, a line connected at one end to the other end of the circuit, and a circuit connected at one end to the other end of the line and at another end to the ground, and a connection state of the emergency stop switch and failure modes of the lines are diagnosed on the basis of a voltage value at the one end of the circuit. Consequently, an operation of the switch and failure modes of a circuit relating to the switch can be diagnosed.
