No, two in parallel will not double, but it will increase reliability an order of magnitude although the actual real life computation is quite complex. If the probability of a switch failure is 1 in 100,000 operations on the first switch, and the probability of a failure on the second switch is 1 in 100,000 operations, the probability that both failures will happen AT THE SAME TIME is 1 in 10,000,000,000. This is a gross simplification but demonstrates the approach.
