Abstract
An in-line switch and mixer control including a first restriction adjacent the outlet of a mixing device having a cleaning fluid and water inlet for controlling the flow rate from the mixer and a second restriction connected to the water inlet for varying the restriction of the water inlet to determine the mixing ratio. Initially, the first restriction is totally closed preventing any flow from the mixer and the second restriction is initially unrestricted. The first and second restrictions include a common actuator for sequentially operating the first and second restrictions to various intermediate restrictive positions.
