Summary:The invention relates to a digital signal output device that outputs a digital signal in accordance with an operation switch. The digital signal output device 1 includes: an operation switch 11 including contacts, a first terminal 21-1 to which a first voltage is applied and a second terminal 21-2 from which the first voltage is outputted when the contacts are closed; a voltage switching unit 12 configured to select a second voltage from among a plurality of constant voltages; a voltage determination unit 13 configured to determine on a designated cycle whether or not a voltage outputted fromthe voltage switching unit 12 has changed from the second voltage; and a digital signal generation unit 14 configured to, when the voltage determination unit 13 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 21-2 and a digital signal indicating the second state when the first
