ABSTRACT:
Apparatus for controlling the supply of electric power to a power consuming appliance (e.g. an electric soldering iron) in dependence on a parameter (e.g. the temperature of the soldering iron) comprises electric circuit means including a thyristor connected in series with the appliance across an AC supply, a first voltage divider including a variable resistor for defining a set point for said parameter, a second voltage divider including a sensor for said parameter and adapted to provide an analogue electrical parameter, and a first and a second transistor having their bases connected respectively to tappings of said voltage dividers defined respectively by a terminal of said variable resistor and said sensor, the emitter of said second transistor being connected to the gate of said thyristor.
