A tilt ball switch has a chamber space, and includes a first terminal, a second terminal including two outer terminal members and an inner terminal member, and a conductive ball movably disposed in the chamber space and convertible between a conducting state, in which the conductive ball is in contact with the first terminal and the inner terminal member so that the first terminal is conductively connected to the outer terminal members, and a non-conducting state, in which the conductive ball is prevented from being in contact with one of the first terminal and the inner terminal member so that the first terminal is prevented from being conductively connected to the outer terminal members.

A push switch contains a case including a containing portion and a sealing groove; a pair of contacts disposed in the containing portion so as to be spaced apart from each other; a movable contact which is disposed above the pair of contacts in the containing portion; a cap including a base portion disposed on the case and a sealing protrusion protruding from a peripheral edge portion of the base portion toward a lower side for liquid-tightly sealing the sealing groove of the case; and a cover attached to the case from an upper side so as to hold the cap on the case. The sealing protrusion of the cap is compressively deformed in the sealing groove of the case, and thereby the sealing groove of the case is liquid-tightly sealed.

A tilt ball switch includes an insulation housing, a conductive ball, and two conductive terminals that cooperate with the insulation housing to define a chamber space. Each of the conductive terminals includes an inner terminal member that has a tapering section. The conductive ball is disposed to be movable in the chamber space and is convertible between a conducting state, in which the conductive ball is located at the tapering sections so that the inner terminal members are conductively connected to each other, and a non-conducting state, in which the conductive ball is separated from the tapering sections so that the inner terminal members are prevented from being conductively connected.

An actuating apparatus having a signal transmitter and a mechanical operating element, wherein the mechanical operating element includes a first position that is stable over time and a second position that is stable over time, wherein the mechanical operating element, in the case of a movement from the first position that is stable over time into the second position that is stable over time, actuates the signal transmitter, and wherein the signal transmitter, upon actuation, causes a first signal change followed by a second signal change of an output signal, and an evaluation circuit detects an actuation of the mechanical operating element based on the first signal change and the second signal change.

A multipolar switch includes a first electrical contact zone connected to a first electrical circuit, and a second electrical contact zone connected to a second electrical circuit. In addition, a first part made from an electrically conducting material is arranged on and at a distance from the first electrical contact zone, and a second part made from an electrically conducting material is arranged on the first part. An electrically insulating layer is arranged between the first part and the second part so as to electrically insulate them from one another. So configured, the first part is configured to be elastically deformed when being mechanically solicited in an actuating direction of the multipolar switch, and the second part is configured to be elastically deformed or be displaced in the actuating direction of the multipolar switch, between a rest configuration and an activated configuration.

This application relates to various button related embodiments for use with a portable electronic device. In some embodiments, a snap clip can be integrated with a button bracket to save space where two separate brackets would take up too much space in the portable electronic device. In other embodiments, a tactile switch can be waterproofed by welding a polymeric layer atop a tactile switch assembly. In this way water can be prevented from contacting moisture sensitive components of the tactile switch assembly. The weld joining the polymeric layer to the tactile switch can include at least one gap to trapped gas surrounding the tactile switch assembly to enter and exit during heat excursions caused by various operating and/or assembly operations.

A push switch includes a housing, a fixed contact member, a movable contact member, and a first pressing member. The housing includes an opening and a compartment, the movable contact member includes a dome that protrudes toward the opening and is invertible, and the first pressing member includes a first fulcrum portion, a first load portion, and a first effort portion. The first fulcrum portion is disposed on one side of the first pressing member to contact the housing, the first load portion is disposed on another side of the first pressing member to press the movable contact member, and the first effort portion is disposed between the first fulcrum portion and the first load portion. Upon the first effort portion being pressed through the opening, the first load portion presses and inverts the dome of the movable contact member, and the movable contact member contacts the fixed contact member.
