An obstruction detecting apparatus, an obstruction detecting system, an electric lifting desk, and an electric lifting cupboard, which relate to the field of obstruction detection and render a higher obstruction detection sensitivity. The obstruction detecting apparatus includes a first housing and a second housing, the second housing being floatingly mounted on the first housing via a first elastic member, on the first housing being provided a circuit board, an obstruction detecting switch connected to the circuit board, and a rocking element rotatably mounted, one end of the rocking element being a free end abutting against the first housing, opposite end of the rocking element being a pressing end pressing down on the obstruction detecting switch, the free end, when being rotated, driving the pressing end to be disengaged from the obstruction detecting switch, whereby an obstruction signal is generated.

A push switch is provided with a knob that causes the movable contact point in contact with the fixed contact point to slide thereon by a push operation of the knob, thereby connecting/disconnecting the movable contact point and the fixed contact point. A sliding direction of the movable contact point is set to a direction vertical to the push direction of the knob, and the push operation of the knob allows the movable contact point in contact with the fixed contact point to slide in a direction vertical to the push direction of the knob.

A switching apparatus includes a switching contact member, a common contact member, a movable contact member configured to electrically connect the switching contact member and the common contact member to each other, and a holding member that holds the movable contact member. The movable contact member includes a switching-side sliding-contact portion configured to come into sliding-contact with the switching contact member and a common-side elastic contact portion that is in elastic-contact with the common contact member. The holding member is rotatable about a rotation axis extending along a direction crossing an extending direction of the movable contact member. Rotation of the holding member allows switching between a first connection state and a second connection state. The rotation axis of the holding member passes through the common contact member, thereby enhancing the stability of conductivity at the operating fulcrum of the movable contact member.

A switching apparatus includes a switching contact member, a common contact member, a movable contact member, and a holding member. The movable contact member includes a main body, a pair of contact pieces juxtaposed so as to clamp the switching contact member, and a common contact portion that comes into contact with the common contact member. The holding member includes a housing portion configured to house a housed portion of the main body, and when the housed portion is snap-fitted into the housing portion, the holding member restricts, for the main body, at least one of displacement in a direction along the moving direction of the movable contact member and displacement in a direction perpendicular to the moving direction while allowing a predetermined displacement in a direction perpendicular to both of the directions.

A switch mechanism of providing dynamic pattern effect is applied to an electronic device and includes a case, a total reflection component, a semi-reflection component, an actuation module and an operation component. The total reflection component is movably disposed inside the case. The semi-reflection component is disposed inside the case and relative to the total reflection component. The actuation module is connected to the total reflection component. The operation component is disposed on a surface of the semi-reflection component opposite to the total reflection component. The actuation module is selectively driven by the operation component so that the total reflection component can be moved relatively to the semi-reflection component selectively.
