The application provides a pressure sensor and a wearable device. The pressure sensor includes a circuit board and a conducting elastic structure; the circuit board includes an electrode area which includes multiple electrode pairs set at intervals; the conducting elastic structure is set on one side of the circuit board and includes a first area; the first area includes a conducting part; when no pressure is applied to the conducting elastic structure, the conducting part is isolated from each electrode pair, so that each electrode pair is in an off state; when a pressure which is greater than a turn-on pressure threshold is applied to the conducting elastic structure, the conducting elastic structure deforms, so that the conducting part contacts with at least one electrode pair, and at least one electrode pair is turned on; wherein the turn-on pressure thresholds of different electrode pairs are different.

A member has a first recess, a second recess, and a depression. The depression accommodates a movable member and a contact member. Positioned on a bottom surface of the first recess is a first fixture contact, whereas positioned on a bottom surface of the second recess is a second fixture contact. When a pressure receiving section of the movable member is pressed toward a bottom surface of the depression, the movable member is elastically deformed to separate a movable joint from the contact member. When the pressure receiving section is further pressed toward the bottom surface of the depression, the movable member is elastically deformed to separate the first movable contact from the first fixture contact and to separate the second movable contact from the second fixture contact.

A button structure and a terminal using the same are provided. The button structure includes a connecting element, a press element, and at least one elastic element connected to the connecting element and the press element. The elastic element is configured to provide a restoring force after the press element is pressed toward the connecting element. The connecting element is provided with an instruction transmission port and at least one of a current transmission port and a data transmission port. The press element is provided with an instruction triggering port and at least one of a current transmission pin and a data transmission pin. The current transmission pin is electrically connected to the current transmission port to output or input current. The data transmission pin is electrically connected to the data transmission port to output or input data.

The present invention relates to a portable lighting apparatus and more particularly pertains to a two-step switch for portable lighting apparatus and a portable lighting apparatus. The two-step switch comprises a casing, a key, a PCB board and a voltage ring sleeved outside of the key. A first spring is disposed between the voltage ring and the PCB board. A second spring is disposed at an end of the voltage ring which is distal from the first spring. The two-step switch is disposed at the end of the portable lighting apparatus which is distal from the light emitting means thereof. The present invention performs switching control of the portable lighting apparatus by the first spring and the second spring, increases the keystroke between the first step switch and the second step switch, and prevents mis-pressing.

The first switch and the second switch may be fixedly supported by a support structure disposed on a same plane as a mounting plane for the actuator and may be positioned in a single inner space.

According to various examples of the present invention, an electronic device can comprise: a board; a switch unit loaded on at least one surface of the board; a pressure module provided between the board and the switch unit; and a pressure sensing unit formed in at least a partial area of the board, and generating a signal by sensing at least one drive according to the pressing of the switch unit. In addition, the above electronic device can be variously implemented according to examples.

This application relates to a dome switch assembly including a base plate that carries a first contact, and a flexible surface connected to the base plate, the flexible surface formed of a metal material in the shape of a dome. The assembly can include a second contact coupled to the flexible surface, and a sound-dampening pad coupled to the flexible surface and formed of a material having noise-dampening properties, wherein when at least a threshold amount pressure is applied to the flexible surface, the flexible surface changes from the dome shape to a collapsed shape allowing the first and second contact to touch, wherein the sound dampening pad absorbs at least some acoustic energy emitted by the touching of the first and second contacts.

This application relates to a switch that can include multiple settings for controlling multiple functions of a computing device. The switch can include multiple flexible surfaces that each includes a surface contact. When the switch is depressed, at least one of the flexible surfaces can collapse and close a connection of the switch. When the switch is further depressed, multiple flexible surfaces of the switch can collapse and close multiple connections of the switch. As a result, depending on the amount of force by which the switch is depressed, different functions of a computing device can be controlled by the switch.
