Abstract: A digital signal output device includes: an operation switch including contacts, a first terminal to which a first voltage is applied and a second terminal from which the first voltage is outputted when the contacts are closed; a voltage switching unit configured to select a second voltage from among a plurality of constant voltages; a voltage determination unit configured to determine on a designated cycle whether or not a voltage outputted from the voltage switching unit has changed from the second voltage; and a digital signal generation unit configured to, when the voltage determination unit determines that the voltage has not changed from the second voltage, generate on every cycle a digital signal indicating a first state when the first voltage is outputted from the second terminal and a digital signal indicating the second state when the first voltage is not outputted therefrom.
