An in-line pump assembly attachable to a hydration bladder includes an electrically driven pump held in a casing and placed in the flow of hydrating liquid. The pump connects to the outlet of the hydration system. Bulbs at the respective ends of a switch line hold an essentially incompressible liquid. Pinching a bite valve bulb on the output end of the drinking tube cause a switch line bulb on the other end of the switch line to expand, closing a pressure switch and causing the pump to pump liquid from the hydration bladder through the drinking tube. Releasing the bite valve bulb reduces the pressure in the switch bulb, disengaging the switch and stopping the flow of liquid. The in-line pump assembly may be connected to a preexisting hydration system through an adapter.

Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.

A pressure switch device is disclosed. The pressure switch device includes a substrate formed of a flexible material, provided with a hole perforated therethrough, and including a rib extending from an inner circumference of the hole and being bendable toward a sensor disposed adjacent thereto by an external force, a contact portion disposed on the rib and forming a contact point with the sensor by the external force, a holder unit fixed to the substrate to be disposed on a peripheral area of the hole and an upper end of the rib, and a piezoelectric sensor disposed between the substrate and the holder unit, supported by the holder unit, and having a disc shape. A printed circuit board includes the pressure switch device.

A tactile switch on a mobile electronic device having a housing is provided. The tactile switch is comprised of a pressure sensitive interface on an exterior portion of the housing, a switch mechanism, and at least one pathway coupled to the pressure sensitive interface and extending from the pressure sensitive interface to the switch mechanism. The switch mechanism is at a remote location from the pressure sensitive interface. The pathway is formed in an interior portion of the housing. The tactile switch further includes a viscous fluid substantially filling the pathway. The tactile switch is configured such that when pressure is applied to the pressure sensitive interface, the viscous fluid exerts pressure on the switch mechanism, causing the switch to make an electrical contact.

The present application discloses a pressure switch which includes a tube structure, a pressure transmitting assembly, a microswitch, and corrugated sheets. The pressure transmitting assembly disposed inside the tube structure includes a guide rod with a piston, and a fluid chamber providing working pressure is defined between the piston and a fluid inlet. The microswitch is disposed at another end of the tube structure away from the fluid inlet and can be actuated by the guide rod. The corrugated sheets are fixed inside the tube structure and stacked on the piston structure so as to form a sealing and pressure transmitting interface for the pressure switch. Therefore, the pressure switch has good sealing property, good buffering capacity, and enhanced mechanical response rate with the corrugated sheets and is suitable for precision pressure measurement and control in an environment with high pressure and high frequency vibration.
