Abstract: A controller for use in a wet environment, such as a controller for a pool or spa, includes a sensor element that generates an electric field having an active region. For the controller, at least one flexible layer is positioned to overlay the sensor element and surround the active region. With this arrangement, a pocket is established between the flexible layer and sensor element. A control circuit that is responsive to the capacitance between the sensor element and the flexible layer is provided. When the flexible layer is deformed, the capacitance changes and the control circuit generates an output signal that corresponds to a particular switch state for a connected device (e.g. pump or heater). For the controller, the control circuit is designed and/or calibrated to maintain a current switch state output in response to the presence of water on the controller and near the active region.

Abstract: Holding structure includes a gear rack member for coupling with an object for movement therewith. The gear rack member includes a set of a teeth and a cam profile surface. A latch is associated with the set of teeth so as to engage and disengage the teeth. A cam follower is fixed to the latch to engage the cam profile surface thereby defining the engaged or disengaged position of the latch with respect to the teeth. A spring provides torque on the latch. The holding structure is constructed and arranged such that during movement of the object in an intended direction, the latch engages the teeth and is held in the engaged position by the spring so as to stop any movement of the object in a direction that is opposite the intended direction, otherwise, the spring is constructed and arranged to hold the latch in the disengaged position.

Abstract: An electrode assembly for a vacuum interrupter is configured such that supporting members can support most of a contact electrode plate and a supporting electrode plate in an axial direction with coil conductors interposed therebetween. Accordingly, an impact generated between electrode assemblies upon a closing operation of the vacuum interrupter may be evenly distributed onto the supporting members, which may result in preventing each of the electrode plates and the coil conductors from being deformed. Also, the supporting members are inserted into the electrode plates and the coil conductors, thereby effectively preventing a current from flowing via the supporting members. In addition, the supporting member may be wide and large so as to simplify an assembly operation and reduce an assembly time.

The interrupter includes a first contact and a second contact configured to alternatively connect to and disconnect from the first contact. One or both of the contacts are at least partially contained in an arcing chamber. The arcing chamber includes the point at which the contacts connect during current-carrying operation of the interrupter. The arcing chamber is at least partially surrounded by a heating chamber for accommodating a quenching gas. A channel connects the heating chamber and the arcing chamber and is positioned to direct the quenching gas toward the first contact and the second contact arcing area. One or more valves direct gas from the arcing chamber to the heating chamber when the interrupter is operated to interrupt a current.

Abstract: The present invention relates to contactors for unidirectional DC operation with permanent magnetic arc extinguishing. In addition to the blow magnets, the contactors are equipped with compensatory permanent magnets for compensating the magnetic field in the vicinity of the contact bridge in order to prevent contact levitation, i.e., an uncontrolled opening of the contacts that is due to a magnetic force generated by a strong current flowing through the contact bridge. To this end, the compensatory permanent magnets are arranged in the vicinity of the contact bridge and polarized in the opposite direction of the blow magnets. The magnetic field of the compensatory magnets and the current flowing through the contact bridge are generating a magnetic force that acts on the contact bridge and tends to keep the electrical contacts closed.
