A single-hand interdigit-coordinated mobile keyboard input device has a chassis configured to conform to human fingers with a plurality of articulating finger frames connected adjacent to each other, a plurality of user input elements, a processing device, and a signal transmitter. The plurality of user input elements is connected around the chassis in order to capture flexion, extension, adduction, and abduction movements of the plurality of articulating finger frames. The processing device interprets signals received from the plurality of articulating finger frames into desired output communication elements such as text characters. The signal transmitter sends the interpreted output to a computing device.

The present disclosure provides a power supply socket and a power receiving head. The socket includes a power supply socket housing, a conductive member, a switching element, and a control component. The conductive member is provided in the power supply socket housing and can be connected to a conductive portion on a power receiving head. The switching element is provided in the housing and has an output end and a control end, the output end of the switching element is connected to the conductive member. The control component is provided in the housing and connected to the control end of the switching element, and is configured to detect the power receiving head, and control the switching element to be turned on when the power receiving head is detected, and control the switching element to be turned off when the power receiving head is not detected.

An electromagnetic relay 1 includes: a base 28; a pair of fixed contact terminals 22 each including a fixed contact 38 and a first fulcrum 22d fixed to the base; a movable contact spring 18 including a pair of movable pieces, each of the movable pieces including a movable contact 36 contacting and separating from the fixed contact; an armature 16 that is coupled with the movable contact spring, and moves the movable contact spring by a rotary motion around a second fulcrum 16e; an electromagnetic device 31 that drives the armature; and a permanent magnet 12 that is arranged between the pair of fixed contact terminals and between the pair of movable pieces, and generates a magnetic field; wherein the first fulcrum and the second fulcrum are arranged mutually in opposite directions with respect to the movable contact or the fixed contact.

The disclosure relates to an electromagnetic switch, comprising: an armature; a slider configured to manually move to actuate the armature; and a deformable force transfer element positioned between the slider and the armature, wherein the slider is configured to be pressed against the deformable force transfer element to actuate the armature with a press force, and wherein the deformable force transfer element is configured to deform when a press force threshold value is exceeded to limit a transferable force from the slider onto the armature.

A double breaker switch comprises a contact bridge connected to an actuator at a connection point, a first fixed contact, and a second fixed contact. The contact bridge includes a first bridge contact connected to the connection point by a first arm and a second bridge contact connected to the connection point by a second arm. The second arm is longer than the first arm. The first bridge contact electrically connects with the first fixed contact at a first contact point in a closed state of the double breaker switch. The second bridge contact electrically connects with the second fixed contact at a second contact point and a third contact point in the closed state of the double breaker switch.

A method for separating welded contacts in a magnetically actuated switch assembly that includes providing multiple actuator hammer blows to the contacts. The method includes causing the contacts to close using, for example, a manual actuation device and detecting a high current condition that occurs when the contacts are closed. The method further includes electrically actuating the actuator to open the contacts in response to detecting the high current condition and determining that the contacts have not opened in response to the actuator being actuated because they are welded together. The method also includes electrically actuating the actuator to close the contacts when it is determined that they are welded together and again electrically actuating the actuator to open the contacts.

Systems and methods for providing illumination to illuminable portions of keys associated with a keyboard are described. A key disposed on a flexible substrate includes a light guide positioned below a keycap. The light guide includes one or more light extraction features to produce a substantially uniform light distribution of light from a light emitting element at an illuminable portion of the key. In one embodiment, a light emitting element is positioned on the flexible substrate and is optically coupled to the light guide. In another embodiment, a light emitting element is positioned below the flexible substrate and is optically coupled to the light guide via an optical interface.

A touch panel and a display apparatus include a backlight apparatus serving as a supporting substrate, a transparent protective plate that is arranged spaced apart from the backlight apparatus and includes an operating surface on an opposite side of the backlight apparatus; a plurality of vibrators for vibrating the transparent protective plate; and a resilient supporting member arranged between the backlight apparatus and the transparent protective plate to support the transparent protective plate and extend and contract diagonally across a thickness direction of the transparent protective plate.

An electrical contactor, and more particularly, but not exclusively, contactors having improved noise performance.

A relay has a case, a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable touch piece including a first movable contact that is disposed facing the first fixed contact and a second movable contact that is disposed facing the second fixed contact, the movable touch piece being disposed in the case and disposed so as to be movable in a contact direction in which the first movable contact and the second movable contact come into contact with the first fixed contact and the second fixed contact and a separation direction in which the first movable contact and the second movable contact separate from the first fixed contact and the second fixed contact. The first fixed terminal includes a first contact support configured to support the first fixed contact.
