Comparative studies of the switching characteristics of devices based on an open discharge - kivotrons in molecular gases (nitrogen and oxygen), as well as their mixtures with helium - have been carried out. The choice of nitrogen and oxygen is due to the fact that the emission coefficients of electrons under the action of their heavy particles are much higher than for helium. It is shown that for this case, as well as with the predominance of the photoelectronic emission mechanism in helium, it is also possible to create fast switches. Their advantage is significantly lower requirements for the cleanliness of the working environment.
