| 摘要 |
The invention is directed to a rotational speed sensing switch which provides a variable linear displacement of an output member in response to a varying speed rotational input. The switch includes a sensing means, which includes a rotatable rolling element-and-ramp assembly, acting in cooperation with a signaling means which includes an axially movable actuating disc, an output member comprising a switch rod, and a biasing means. The aforementioned improvement over the prior art comprises a regulating means included within the sensing means.
