Finding problem of the reliability measures of the restorable system with load-mixed reserve and individual switches is considered. The aim of the article is the receiption of the correlations allowing to estimate the mean operating time to failure, reliability function and availability function of this system with redundancy ratio m = 2 and individual switches unreliability account. Markovian model of the system is used. System passages graph – "diagram of birth and death". As the result of problem solution the expressions for calculating above-mentioned reliability measures, estimations of the reliability gains to mean operating time to failure, failure probability and downtime rate from considering system application are obtained. This expressions may be used with any type of a reserve on a load and the execution of received assumptions.

Key words: reliability, redundant restorable system, load-mixed reserve, individual switches, mean operating time to failure, reliability function, availability function, reliability gain to mean operating time to failure, reliability gain to downtime rate.
