Abstract
A device capable of sensing forces exerted by fluids, particularly liquids, and thus may be used to sense fluid level and fluid flow. Preferred embodiments of the device include a switch means capable of being actuated without the exertion of substantial mechanical force thereon and an elongated body of low mass mounted for pivotal movement about an end thereof with switch actuation means at an end thereof in operative relation to the switch means only when the axis of elongation of the body is aligned with the switch means. Features of the device provide reduced inertial effects and reduced gravitational force requirements, as well as reduced wear, in operation.
