An item such as a fabric-based item may have one or more input devices. The input devices may have terminals that are electrically coupled to control circuitry. The control circuitry may make resistance measurements, capacitance measurements, and other measurements on the input devices to determine whether the input devices have been pressed by a user's finger or have otherwise received input. The input devices may be used to form an array of switches for a keyboard, may form buttons on an electronic device housing or case, may be part of an item of clothing, or may be incorporated into other items such as fabric-based items. The input devices may have collapsible fabric structures such as collapsible fabric domes. The terminals of the input devices may be formed from conductive strands of material in the fabric domes or may be supported by other structures that buckle under applied pressure.

The invention relates to the field of switches, and particularly provides a switch for a vehicle and a vehicle. The invention aims to solve the problems of switch zero drift and shaking caused by the existence of a dimensional deviation of a switch of an existing vehicle. To this end, the switch according to the invention comprises a pressing rocking bar, a first push rod, a second push rod, a first elastic member, a second elastic member, a first limiting body, a second limiting body, and a housing, wherein the pressing rocking bar is pivotally connected to the housing; the first push rod and the second push rod respectively run through the first limiting body and the second limiting body and abut against bottoms of a first end and a second end of the pressing rocking bar, and the second push rod abuts against the second limiting body; and the first elastic member and the second elastic member are fixedly arranged and respectively connected to bottoms of the first push rod and the second push rod, torque of the second push rod acting on the second end is greater than torque of the first push rod acting on the first end, and a moving gap is reserved between the first limiting body and the first push rod in a pressing direction of the first push rod. Switch shaking is prevented and switch position accuracy is ensured.

A controller includes a key top, a substrate, and an elastic member. The elastic member includes a pressed portion, a base, a skirt portion, and a pressing member. The substrate includes a contact. When viewed in the first direction, the pressing member is surrounded by an outer peripheral edge of a prescribed region. In the second direction, a distance between an end of the outer peripheral edge of the prescribed region on a side of a swing center of the key top and an end of a top surface on the side of the swing center is longer than a distance between an end of the outer peripheral edge of the prescribed region opposite to the swing center and an end of the top surface opposite to the swing center. In the second direction, the contact is located closer to the swing center than the top surface.

A waterproof board switch includes a print circuit board, a bottom coverlay, an insulation adhesive film having a dome hole and being thermo-compression bonded to the front surface of the print circuit board, a metal dome inserted into the dome hole, and a top coverlay coupled to the insulation adhesive film and the print circuit board to cover the dome hole and surround sides of the insulation adhesive film and sides of the print circuit board. The top coverlay is thermo-compression bonded to the top of the insulation adhesive film, the sides of the insulation adhesive film, and the sides of the print circuit board by thermo-compression bonding to seal a space on which the metal dome rests, thereby preventing an introduction of contaminant into the metal dome and the print circuit board.

Implementations of a multi-pole dome switch configured to simultaneously, or nearly simultaneously, close or open two separate circuits are provided. In some implementations, a multi-pole dome switch may comprise a tactile metal dome and a conductive insert that are separated by an insulator. In some implementations, when the dome is depressed, the dome and the conductive insert are configured to simultaneously, or nearly simultaneously, make conductive contact with two traces of a first circuit and two traces of a second circuit, respectively, positioned thereunder on a PCB. In this way, the multi-pole dome switch is able to simultaneously, or nearly simultaneously, close two separate circuits. Succinctly put, in some implementations, the multi-pole dome switch may be configured to act as a double-pole, double-throw switch.

A switch device includes a substrate having at least one fixed contact and an inflow/outflow section provided with at least one through-hole, and a rubber contact to cover the substrate. The rubber contact includes at least one moving section disposed facing the respective at least one fixed contact, the moving section elastically deforming such that moving contacts corresponding to the respective fixed contacts are capable of contacting/separating, an in/out section disposed facing the inflow/outflow section and configured to form a space with the inflow/outflow section, a flow path section configured to form a flow path to connect the in/out section and the at least one moving section, and at least one chamber section having a space larger than a space occupying along representative length of the flow path section on a portion of the flow path section, and having strength such that a shape of the space is maintained.

The present disclosure relates to a switch assembly for a motor vehicle component, including: an electronic basic body for arranging a contact member; an actuating member for actuating the contact member; a web associated with the actuating member, including a web portion with a web stop; a flexible switching mat having a basic portion for arranging the actuating member and the web; an operating member having an operating portion with an operating stop and an operating counter-stop disposed opposite to the web stop; a support member connected to the basic body or the switching mat having a support portion with a support counter-stop that contacts the operating stop in a non-actuated state of the switch assembly; wherein the web provided on the basic portion is arranged to be spaced apart from the actuating member provided on the basic portion, wherein the web encloses the actuating member at least partially.

Systems and methods for a hack-proof security keyboard are described. In some embodiments, a keyboard module may include a first circuit configured to detect activation of a plurality of keys and a second circuit configured to detect activation of a subset of the plurality of keys, where the second circuit overlies the first circuit. In other embodiments, a method may include detecting an electrical signal received from a secondary membrane of a keyboard, where the keyboard includes a primary membrane configured to detect individual activation of any of a plurality of keys, and where the secondary membrane is configured to output the electrical signal in response to concurrent activation of a subset of the plurality of keys. The method may also include performing a selected action in response to the detection.

A to-be-depressed member includes an elastic dome. A sectional shape of the dome orthogonal to an axis line (X2) of the dome is line-symmetric about a symmetry axis (Ax). The dome has a three-dimensional shape that is symmetric with respect to a virtual plane (Sx) containing the symmetry axis and the axis line. During a swinging movement responsive to a depressing operation, an opposed surface of an opposed member relatively approaches and contacts a distal end of the dome to deform the dome so as to generate a reactive force. As for an angle defined between the axis line of the dome and a normal line (X1) of the opposed surface, the angle (0) in an initial state falls in a range from a first angle variation amount from the initial state to a first-contact state to a second angle variation amount from the initial state to a depression-completed state.

A push switch includes a base member including a depressed accommodating part, a fixed contact member provided and exposed in the accommodating part of the base member, a movable contact member installed in the accommodating part and including a dome part configured to be reversible to contact the fixed contact member, a sheet member installed to cover the accommodating part and hold the movable contact member, a pusher member installed between the top of the dome part and the sheet member, and a sheet-shaped reinforcing member formed of a material having a lower coefficient of thermal expansion than the sheet member. The reinforcing member is installed over the sheet member.
