ELECTRONIC SWITCH Russian patent published in 2005 - IPC

FIELD: remote commutation in alternating or direct current grids.

SUBSTANCE: electronic switch has receiver for remote receipt from external control panel of encoded signal and transformation of it to pulse series, delay device, input of which is connected to output of receiver, first pulse counter, force block in form of one or more force keys for commutation, of appropriately one or more loads, power source and generator of signal of starting setting. Also provided is second pulse counter, connected by counting input to output of first pulse counter, and by outputs to inputs of appropriate force keys, while first pulse counter by its counting input is connected to output of receipt device, by zeroing input - to output of delay device, by count forbidding input - to own output, and zeroing input of second counter is connected to output of signal generator of starting setting.

EFFECT: higher reliability and broader usability range.
