<p>The pressure switch has an electrical pressure sensor for producing an electrical pressure-dependent signal, a control and/or setting device for specifying at least one switching threshold and at least one electrical switch output. The switch can be set by operating a control device (16-18) so that a signal generated in response to an instantaneously applied pressure is stored as a first stored pressure value and a signal for a subsequent pressure is stored as a second stored pressure value, whereby the values define the pressure switching threshold(s) for operating mode.</p> |
