<p>A micromechanical press switch wherein a micromechanical pressure transducer produced on a silicon chip serves as switching element. With a view to eliminating the drawbacks of mechanical and electrical switches, in the press switch of the invention the switching element (2,2; 6) has in part at least been formed on the same silicon chip (1) on which the electronic circuitry (12, 13, 16) receiving and interpreting the switching information has been integrated. The switch may be used with advantage on landing levels for recording a lift's outside calls and in the lift car to record its inside calls and for inputting them to the lift control system.</p> |
