Changeover relay contact

It implements the operation of switching input contacts depending on the value at the control winding of the relay: where y(t) is the output signal of the block, x_r(t) is the value (state) of the relay, x₁(t), x₂(t) are the input signals of the block. To view the structure of the algorithm, right-click the block and select the item Actions → Enter to the submodel. Contact switching is implemented using the Key-3 block, signal transmission from the control winding of the relay is implemented using the From memory block.
