A system and method for connecting supply power to motor control components includes use of a motor control center subunit with moveable supply power contacts. After a motor control center subunit is secured into a motor control center compartment, the supply power contacts may be advanced to engage supply power buses. For disconnection, the supply power contacts may be retracted and isolated from the buses before physical removal of the subunit.

An operating device contains a cover plate having an opening, a rotatable operating element having an operating head on the cover plate, and a shaft running through the opening. Behind the cover plate and at a distance therefrom, there is a circuit board having an opening through which the shaft extends. The operating device includes a tube element which has a hollow-cylindrical base body that runs, between the cover plate and the shaft of the operating element, at least partially through the opening of the cover plate, and a radial inner side that forms, between the tube element and the shaft of the operating element, an inner flow channel that runs through the opening of the cover plate and past the opening of the circuit board, to protect the circuit board against extraneous substances which may enter the operating device through the opening of the cover plate.

A multi-gear brightness adjustment circuit board, and a multi-gear battery holder structure, which through adding the automatic control gear AUTO conductive contact piece and a light spot dot-circle pattern composite conductive contact piece on the circuit board, the gear can be automatically adjusted when the solar cell is used for power supply. Ensuring that the output light power meets the needs of ambient light, rationally use electric energy, which is conducive to energy saving; at the same time, the mode switching of the shooting target is integrated, which reduces the parts of the sight and makes the sight more compact.

A scrolling shifter assembly having a housing rotatably supporting a scrolling wheel having a knurled exterior edge accessible to a vehicle operator, the scrolling wheel also including an annular side detent profile. A magnet is positioned in proximity to a sensor mounted to a printed circuit board (PCBA) within the housing and displaces relative to the sensor in response to rotation of the scrolling wheel. A display component is mounted in proximity to the PCBA. At least one haptic biasing component including any of spring loaded pawl or wave spring is supported within the housing and biases against the detent profile such that, and upon the operator actuating the scrolling wheel, the pawl is caused to displace relative to the profile in order to incrementally rotate the wheel, the magnet rotating relative to the PCBA sensor to cause an associated processor to electronically instruct a shift change to an engine control unit.

A rotary knob for operating an electronically actuable deadbolt is described herein. According to some embodiments, the rotary knob includes a chassis, an outer wall rotatably coupled to the chassis about a central axis of the knob, a cantilevered beam attached to an inner surface of the outer wall and extending towards the central axis of the knob such that the beam is configured to rotate with the outer wall about the central axis, a circuit board coupled to the chassis, the circuit board including signal traces, and an electrical contact extending from the cantilevered beam in a direction toward the signal traces and electrically connectable with the signal traces. A controller of the rotary knob is configured to determine a position of the deadbolt based on at least the state of the electrical connection between the electrical contact and the signal traces.

An electrical appliance device contains a knob which has a knob front assembly with a front cover assembly, a knob bracket, and a display module assembly disposed between the front cover assembly and the knob bracket, and a knob rear assembly including a circuit board and a hollow rotary encoder. The rotary encoder is mounted on the circuit board. The electrical appliance device further has a panel with an opening. The knob front assembly at least partially passes through the opening such as to be mounted to the knob rear assembly.

An automatic transfer switch (ATS) utilizing molded case circuit breakers (MCCB) or molded case switches (MCS) to connect and disconnect an electrical load to a Normal power source and a Standby power source. The ATS comprising two MCCB or MCS mounted back-to-back one connected to a Normal power source and the other to a Standby power source. Bus bars electrically connect the poles on the load side of the MCCB or MCS connecting the ATS to a load. A rotating cam drive mechanism drives Toggle Levers with attached stored energy opening springs toggles to open and close the MCCB or MCS through the leverage of fulcrum points. A ratchet mounted on the output shaft of a unidirectional gear motor rotates the cam drive mechanism. An interlock bar prevents both MCCB from closing at the same time.

Keyboards, input devices, and related systems include key mechanisms with keycaps and actuators that provide adjustable feedback in response to user input. The actuators are controllable to provide variable tactile force or audible feedback that is dependent upon the user input. Encoders are able to transduce a location or relative position of a keycap as it is being pressed over time, and a signal is provided to actuators to cause them to provide feedback corresponding to the position of the keycap as it moves. The feedback can change the feel or sound of the keycap based on the keycap positions, time of operation, velocity, user identity, and other factors. Thus, the feel or sound of a keyboard or related input device can be adjusted electronically for efficient testing and increased user customization and feedback modes.
