Abstract

The circuit has an oscillator with a detection coil and a first switch element that outputs the control signal when the coin is inserted. A first stage sets the oscillator working point in the rest state. A second stage has a switch element that acts as a constant current source in the rest state. Its current changes when a coin is inserted depending on oscillator output voltage so the first switch element switches and outputs a switch-on signal. The circuit has an oscillator (1) with a coil for detection coin insertion whose output signal is changed by the coin and a first electronic switch element (Q4) that outputs the control signal when the coin is inserted by changing its control voltage. A first stage (2) sets the oscillator working point in the rest state. A second stage (3) connected to the oscillator output has a second electronic switch element (Q2) and is connected to the first stage so that the second switch element acts as a constant current source in the rest state. The current in the switch element changes when a coin is inserted depending on the oscillator output voltage so that the first switch element switches and delivers the switch-on signal.
