A load limit system is provided for a linear actuator. An interface is athed to the linear actuator and is disposed between first and second spring assemblies. A first sensor senses a first amount of linear compression of the first spring assembly along a first direction. A second sensor senses a second amount of linear compression of the second spring assembly along a second direction. Movement of the linear actuator in the first direction ceases whenever the first amount of linear compression is sensed. Movement of the linear actuator in the second direction ceases whenever the second amount of linear compression is sensed.

Load limit system for mechanical linear actuator

Hand-held shower head

A hand-held shower head includes a housing which is cylindrical in shape and has a frusto-conical portion with a single orifice nozzle in the center thereof. A push-button actuator is positioned on the cylindrical side portion which in turn actuates a valve mechanism through a diaphragm seal. Water flows from an inlet opening through a lightly biased, normally closed valve which is operated through a plunger connected via the diaphragm to the push-button actuator, and out through a flow restricter and the single orifice nozzle. The push-button actuator is provided with stop means to limit the depression of the actuator.
