There are three jacks on the back of the Quadstick. The bottom jack provides two switch inputs. The center jack connects to the Lip sensor. The top jack can be ordered as either two switch inputs or two relay outputs.
If you would like to use the Quadstick WITH adaptive switches, the Inputs option would give you two more inputs for a total of four switch inputs and zero relay outputs.
If you would like to use the Quadstick AS an adaptive switch with other devices that work with them, then the Outputs option would give you two relays outputs and two switch inputs.
