Abstract

Improvements in non-contact emitters of orders, of the type comprising a capacitive control element preferably in the form of a plate forming the variable element of an electric circuit, powered by a high-frequency current source, for signaling installations of control with non-contact control elements, especially for elevator controls, characterized in that the capacitive control element bypasses the resistances of a voltage divider consisting of a series connection of two resistors and a capacitor, connected to a power source high frequency, whose high frequency voltage can be taken at the resistance of the standing point and whose magnitude depends on the pulsation state of the pulsating organ and is passed through rectifier and rectifier means to direct control voltage at the input of an operational amplifier, whose second input for the adjustment of the connection sensitivity is applied to a variable pre-voltage and in whose output a bivalent control voltage can be taken for the control of downstream control elements of order processing.
