The switch assembly 12 is seated on the sleeve 28 such that the primary magnet 20 of the magnetic assembly 18 is surrounded by the sleeve 28.

A proximity sensor includes a conductor, a receiving electrode, and a first transmission electrode. The conductor has an upper surface. The receiving electrode is separate from the upper surface of the conductor in an upward direction and extends along a first direction. The first direction is orthogonal to the upward direction. The first transmission electrode is separate from the upper surface of the conductor in the upward direction and extends along the first direction. The first transmission electrode and the receiving electrode are aligned with each other in a second direction. The second direction is orthogonal to both the upward direction and the first direction. The first transmission electrode has an upper surface having a shape bulging in the upward direction in a cross section orthogonal to the first direction.

Magnetic coupling devices are disclosed which may be configured in at least three states. The various states may be provided through one or more of altering a position of a permanent magnet relative to another permanent magnet and altering a current level in a coil surrounding a permanent magnet.

A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.

A vehicle is provided. The vehicle includes an electronic control unit and a pedal assembly. The electronic control unit switches from a powered off state to a powered on state during predetermined intervals. The pedal assembly includes pedal arm, a target, and a switch. The pedal arm moves between a plurality of positions. The target moves with the movement of the pedal arm. The target generates a magnetic field strength. The switch activates when the magnetic field strength of the target exceeds a predetermined threshold. When the switch activates, a signal is sent to the electronic control unit to activate the electronic control unit from the powered off state to the powered on state.
