<p>A compact pressure switch that causes little error in the operating point of the switch and that has resistance to dust, water, and chemical solutions is provided. The pressure switch includes a housing (2) formed of a resin having chemical solution resistance, a pressure sensor (3) that detects the pressure of a fluid, a separator (4) that is formed of a resin having chemical solution resistance and that prevents the fluid from coming into contact with the pressure sensor (3), and a circuit unit (5) that outputs on and off signals based on the output of the pressure sensor (3). At least the pressure sensor (3) and the circuit unit (5) are disposed in a sealed space (S) formed by the housing (2) and the separator (4).</p> |
