A rocker switching control element for electrical sliding roofs on a vehicle overhead panel has an actuation rocker formed as a switch with switching positions and is arranged on a substantially planar control panel. The actuation rocker is recessed such that it does not project beyond the panel edge region. The transition between the panel edge region and the actuation rocker is formed with the panel edge region forming over a first width a goblet-like edge set back by a first depth, and an adjoining edge, separated by a gap of width, of the actuation rocker, which edge is recessed by more than the first depth in the non-actuated state and set further back continuously over a second width by a second depth. The recess is shaped overall such that inadvertent actuation of the actuation rocker by an object significantly larger than a human finger is prevented.

A keyswitch structure includes a keycap layer having a keycap region and a peripheral region adjacent to the keycap region, a circuit layer disposed under the keycap layer, a haptic actuator electrically connected to the circuit layer, a supporting structure layer being disposed under the circuit layer and having an accommodation space for accommodating the haptic actuator, and an adhesive layer disposed between the keycap layer and the circuit layer corresponding to only the peripheral region.

A keyswitch structure includes a keycap layer having a keycap region, a circuit layer disposed under the keycap layer, at least a haptic actuator disposed under the circuit layer and electrically connected to the circuit layer, a cushion layer disposed under the circuit layer and having an accommodation space for accommodating the haptic actuator, a sensing unit disposed under the cushion layer, and a control circuit coupling the sensing unit and the circuit layer, wherein when an external force is applied and delivered through the cushion layer to trigger the sensing unit, the sensing unit outputs a trigger signal, and the control circuit receives the trigger signal and outputs a driving signal to drive the haptic actuator to vibrate.

An interlock apparatus of a ring main unit is provided. The interlock apparatus may be provided between a plurality of switches which are included in the ring main unit and are adjacent to each other, and when one switch is controlled to a closed state and is connected to a power supply source, the other switch adjacent to the one switch is prevented from being connected to the power supply source, thereby preventing the plurality of switches from being simultaneously connected to the power supply source.

A method for toggling between different working states of an electronic device includes detecting temperature and pressure data from at least one sensor when a home button of the electronic device is pressed, and recording a duration of the pressing when the sensed data is within predetermined values. A current state of the electronic device and/or display screen is detected, and a working state is changed from the prevailing state to an opposite state, in dependence on the recorded duration of the pressing.

A door lock switch lockout device for preventing unintentional locking or unlocking of a vehicle includes a housing that is box shaped. The housing has a top, an open bottom, an open front, a back, and opposing sides. A lip is coupled to the back and the opposing sides adjacent to the open bottom. A fastener is coupled to the lip. The housing is configured to be placed over the door lock switch of a vehicle with the door lock switch extending into an interior space of the housing through the open bottom. The fastener is configured to fasten the housing to the vehicle. The door lock switch is substantially covered by the housing to deter unintentional locking or unlocking of the vehicle. The open front allows access to the door lock switch for intentional locking or unlocking of the vehicle.

A switch includes a fixed contact part including a fixed contact, a movable contact part including a movable contact, a control button, an operation part including a first end and a second end, and a lock. When the first end is pressed, the control button is pressed by the operation part, the movable contact touches the fixed contact, and the switch becomes an ON state. While the movable contact and the fixed contact are in contact with each other, a first protrusion of the lock touches an engaging part of the control button to limit movement of the control button and maintain the ON state. When the second end is pressed, the operation part touches a second protrusion of the lock and moves the lock in such a direction that the first protrusion moves away from the engaging part, and the switch becomes the OFF state.

Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, a negative pressure source, a canister, an antenna, and one or more controllers. The negative pressure source can provide negative pressure via a fluid flow path to a wound dressing. The canister can be positioned in the fluid flow path and collect fluid removed from the wound dressing. The antenna can be supported by the housing and wirelessly communicate with an electronic device. The antenna can be oriented in the housing to face downward toward the ground when the negative pressure source is providing negative pressure. The one or more controllers can activate and deactivate the negative pressure source and transmit first data to the electronic device using the antenna or receive second data from the electronic device using the antenna.

An embodiment of an outdoor unit of a climate control system includes a refrigerant compressor, an electric motor configured to drive the refrigerant compressor, and a variable frequency drive (VFD) electrically coupled to the electric motor and configured to be electrically coupled to a ground-fault circuit interrupter (GFCI). The GFCI is electrically couped to an electrical power source. The VFD has circuitry that includes an electromagnetic interference (EMI) filter configured to at least partially filter electromagnetic interference generated by the VFD, and an inductive device that is configured to be electrically coupled to the GFCI in parallel with the EMI filter. The inductive device is configured to at least partially dissipate current discharged from the EMI filter in response to a de-energization of the electrical power source, to thereby prevent a trip of the GFCI upon re-energization of the electrical power source.
