A flexible switch has a deformable body and a plurality of electrodes, at least one of the electrodes being provided on the deformable body. The switch has a first state in which the electrodes are spaced apart and a second state in which the electrodes are in electrical contact, and the switch is configured to allow movement between the states when a force is applied to or removed from the deformable body.

A mounting system for mounting a pressure switch to a mounting body without using screws or brackets. The mounting system includes a support physically supporting the pressure switch on the mounting body, a conduit carrying a pressure signal from the mounting body to the pressure switch, and a connector extending between and connecting the support to the conduit. The support and conduit may have ends constructed of synthetic rubber to frictionally engage support and conduit mounts, and the support and conduit may have approximately the same length and/or the same cross-sectional shape. The mounting body may be a draft inducer, a condensate collector box, or a drain trap in a furnace.

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.

A pressure switch for controlling application of negative pressure to dressing disposed adjacent a tissue site is disclosed. The pressure switch comprises a body having a base, sidewalls extending from the base to an open end, and an inlet coupled to the dressing and forming a passage through the body. The pressure switch further comprises a diaphragm closing the open end of the sidewalls and forming a vacuum chamber with the body, wherein the inlet fluidly couples the vacuum chamber and the dressing. The pressure switch further comprises a valve disposed in the passage and configured to restrict the flow of gas through the passage so that a switch pressure developed in the vacuum chamber as a result of the application of negative pressure to the dressing lags a wound pressure at the tissue site to delay, wherein the diaphragm is adapted to be operatively responsive to the switch pressure to move between a relaxed position and a compressed position as the negative pressure increases and decreases. This pressure switch further comprises a switching element coupled to the diaphragm to turn on the negative pressure in the relaxed position and turn off the negative pressure in the compressed position. In another example, a method for controlling application of negative pressure to dressing disposed adjacent a tissue site using a pressure switch is disclosed. In another example, a system for applying negative pressure to a tissue site using a pressure switch is disclosed.

Examples are disclosed that relate to magnetically aligned switching circuits. One disclosed example provides an electronic component comprising a first terminal, a second terminal, and a deformable host material arranged between the first terminal and the second terminal. Aligned magnetically within the host material is an ensemble of particles each comprising a ferromagnetic material, each particle having greater electrical conductivity than the host material. The ensemble of particles is configured to form at least one complete conduction path from the first terminal to the second terminal.

The present utility model discloses an air pressure switch, a power supply device using this air pressure switch, and an electronic cigarette using this power supply device. The air pressure switch includes a main body that includes a sensing area that will be triggered under negative pressure. The air pressure switch further includes a flexible protection film installed on the main body and at least the outer surface of the main body where sensing area is provided so that a first cavity is enclosed by the protective film and the surface of the main body where the sensing area is provided and formed. The protective film deforms away from the main body under the external suction force, so that the airflow in the first cavity can partially flow into the space generated by the deformation of the protective film.

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.

Systems (100) and methods (2400) for operating a submersible switch positioned below a body of water's surface. The methods comprise: deflecting a semi-rigid top wall of the submersible switch's cap towards a center of the switch when hydrostatic pressure is applied thereto; directly applying a pushing force by the submersible switch's cap onto an actuator of an internal switch disposed in a body of the submersible switch; and causing an operational state change of the submersible switch in response to the pushing force being applied directly to the actuator of the internal switch.
