A rotary switch would be used for a selector. For example - a munitions switch with six positions for six different options would be operated by a rotary switch. Each of the six detents on the switch would be wired to a seperate input for the card - placing the switch in position A selects Guns, in position B selects Cannon, etc etc.<BR>

It would be used to, for example, adjust the HDG bug on an ADF dial. There are no discrete positions you could wire to a rotary switch - as long as you keep turning the knob one way, the bug will just go round and round and round.<BR>
