PROBLEM TO BE SOLVED: To provide a pressure switch device capable of stably operating apparatuses even when the chattering of electric switch sections occurs, thereby miniaturizing a pressure switch. SOLUTION: This pressure switch device is provided with the pressure switch 500 having electric switch sections 541 and 542 outputting the signals for opening or closing the inversion plates 511-513 inverted or returned according to the fluid pressure and contact point sections 541c, 542c, 542d to control the apparatuses 200 and 400 and a control means 800 receiving the signals from the electric switch sections 541 and 542 when the inversion plates 511-513 are inverted or returned to hold the operating state of the apparatuses 200 and 400 determined by the opening or closure of the contact point sections 541c, 542c, 542d for the prescribed period T longer than the inverting time t1 or the returning time t2 of the inversion plates 511-513.
