A switch, keyboard and associated methods are provided. In one implementation, the switch includes a housing having a protruding portion configured to be received in an aperture formed on a substrate, a plunger operable to move with respect to the housing, a first contact member located in the housing, and a second contact member extending from the protruding portion of the housing. The second contact member is operable to, based at least in part on the plunger being moved in a first direction, deform to a predefined extent to electrically contact the first contact member. The switch provides a low profile appearance but not compromising the smooth and quickly responsive striking motion for a mechanical switch, such that a clean design can be provided while the input experience and durability are maintained. A keyboard is also provided.

Provided are a control box and electric furniture. In the control box, a wireless charging assembly is pressed downward by an external force such that the wireless charging assembly moves downward relative to the control box body to drive or push the pressing portion toward a control switch. When the pressing portion abuts against the control switch, the control switch acts. After the external force is removed, the wireless charging module moves away from the control switch under the action of an elastic resetting portion so that the pressing portion is separated from the control switch.

A key structure includes a circuit board, a housing, a first metallic element, a second metallic element, a keycap and a conductive strip. The conductive strip is disposed within the housing. The first metallic element and the second metallic element are electrically connected with the circuit board. The housing is disposed on the circuit board. The keycap is fixed on the housing. While the keycap is depressed, a first end of the conductive strip is pressed by the triggering part and the conductive strip is swung relative to the housing. Moreover, a second end of the conductive strip collides with the second metallic element. Consequently, the key structure is triggered. When the second end of the conductive strip collides with the second metallic element, a click sound is generated.

Disclosed is a microswitch that allows the setting of the microswitch to be detected. The microswitch includes a conducting element movable along a surface that includes at least one conducting track that is contacted by the movable conducting element. Actuating the microswitch moves the movable conducting element along the surface resulting in electrically connecting or disconnecting two electrical tracks and causing electrical switching. In addition, the contact surfaces electrically connected by the conducting element may have different electrically conductive regions such that moving the connected surfaces changes the electrical resistances. Different switch positions can be determined by measuring resistance.

A computer mouse that includes a plurality of tunable switch assemblies is disclosed. According to certain embodiments, the tunable switch assembly comprises a plurality of tunable switches and a rotatable wheel casing that houses the plurality of tunable switches. Each tunable switch of the plurality of tunable switches is distinct from any other tunable switch in the plurality of tunable switches in a given tunable switch assembly of the plurality of tunable switch assemblies, according to certain embodiments.

A state and operation indicator for a snap switch is provided. Presently, instrumentation is often needed in order to determine if a snap switch is malfunctioning. Information may be provided on a control panel inconveniently positioned remotely as compared with the location of the snap switch itself. This disclosure provides for an indicator of the state and operation of a snap switch, which does not require the use of instrumentation, and which is proximate the snap switch. This indicator can be used in both alternating and direct current circuits. When the common terminal of the switch is energized an associated light can provide a cue that the power is on. The state and operation indicator can also have either a light associated with the normally open terminal, a light associated with the normally closed terminal, or both. These lights can respond to indicate the state and operation of the switch.

A method of manufacturing a waterproof board switch according to the first embodiment comprises the following steps: (A) arranging a plurality of print circuit boards on a board plate, each of the print circuit board having a top pattern on a front surface and a bottom pattern on a rear surface; (B) insulating the rear surface of the print circuit board; (C) forming a board ass'y by thermo-compression bonding an insulation adhesive film having a dome hole to the front surface of the print circuit board; (D) forming a plurality of board holes near both edges of the dome hole on the board ass'y; (E) resting a metal dome on the dome hole such that the metal dome is able to be in contact with the top pattern; (F) arranging a top coverlay having bigger width than the insulation adhesive film on the board ass'y such that the top coverlay covers the dome hole; (G) arranging a thermoplastic resin above the top coverlay, arranging a top jig above the thermoplastic resin, arranging a bottom jig below the board ass'y and then applying thermo-compression to the thermoplastic resin by means of the top jig and the bottom jig; (H) making the thermoplastic resin having flowability flow from the top coverlay to the board hole by the step (G) such that ends of the top coverlay are bended so as to be in contact with sides of the board ass'y and then are inserted into the board hole, and then thermo-compression bonding the top coverlay to the top of the board ass'y and the sides of the board ass'y by means of the thermoplastic resin; and (I) separating the board ass'y to which the top coverlay was bonded from the board plate after the step (H).

A pushbutton switch includes a pushbutton unit and a resilient member. The pushbutton unit includes a mounting seat and a pushbutton covering the mounting seat. The resilient member has a switch contactor, two resilient arms extending respectively from opposite ends of the switch contactor, two abutment segments engaging the limiting seat, and four sustainment segments extending away from the abutment segments and inclined toward the switch contactor. When the pushbutton is pressed to push the sustainment segments, the resilient arms are deformed to have a resilient force for urging the pushbutton away from the limiting seat, and to drive the switch contactor to contact and move an activator of a switch assembly.

An electric switch has a housing with an upper surface through which a actuating plunger extends at a position close to a side surface. The actuating plunger is arranged to operate a switching element disposed inside the housing. An actuating lever is fixed to the side surface adjacent the plunger such that the actuating lever extends over and beyond the upper surface of the housing. A stop for the actuating plunger is arranged inside the housing. With this switch the actuating travel is extended solely in relation to the switch. Furthermore a long over-travel exists following switching, wherein any forces which might occur through improper use in relation to the switch do not cause any damaging effects to the switching element.
