Abstract
A mechanical timer to control multiple steps of a process comprising a first cam having a shaft, and a second cam having a shaft, wherein the shaft on the first cam extends into the shaft of the second cam. The rotational relationship between the first and second cams determines the length of time for at least one process step. First and second user adjustable elements are attached to the first and second cams. These user adjustable elements do not require any disassembly of the mechanical timer by the user or require any tools. A plurality of switches engage the cams to control various process steps.
