The 1:2 Selector building block is used to select one of two Number values.
A 1:2 Selector building block has one ON/OFF input, two Number inputs, and one ON/OFF output. The "SEL" input value is used to select which value from the two Number inputs will be used as the output value. If the "SEL" input is ON, then the output value will be set to the value of the "ON" input. If the "SEL" input is OFF, then the output value will be set to the value on the "OFF" input.
A 1:2 Selector building block has no properties to configure.
