ABSTRACT:
A predetermined limit in the rotation of a manually rotatable control shaft is established by a special knob having a speed nut which secures the knob to the shaft, and an interrupted circular slot in the knob, concentric with the shaft, for cooperating with a fixed projection extending parallel to the shaft and into the circular slot. The device is described as usable in a thermostatically controlled heating system with an auxiliary control for improving efficiency.
