The light bulb device with functional features may include one or more features such as a dimmer function for the light source, an on/off function for the light source, a charger function for external devices using an USB port, an electrical outlet, a night light, etc. The light bulb thus converts the AC voltage in the conventional light socket to one or more usable voltages for electronic features therein or other electronic devices. One such feature is a dimmer function, another feature is one or more USB ports for charging or operating other devices such as video camera. Also, a Bluetooth connection may allow the device to act as a speaker or projector or a clock. A video monitoring feature may be included within the device that can be monitored via Bluetooth connection to a smart phone.

A gear structure and a dimmer and speed control switch, wherein the gear structure includes a plurality of positioning grooves and a gear switching component, and the plurality of positioning grooves are sequentially spaced apart on the housing; the gear switching component is movably Installed on the housing, it includes a positioning component and a biasing component connected with the positioning component. The positioning component has a first position that is positioned and matched with the positioning groove and a second position separated from the positioning groove. The biasing component applies a biasing force on position component that moves it toward the first position, the gear structure mentioned above can ensure accurate gear positioning during the operation of the dimmer and speed control switch, and is not prone to misoperate, which is convenient for users, and coordinated positioning grooves and positioning parts have the advantage of simplified structure.

A switch device includes at least one switch element actuated by a cam of a camshaft. The cam is a three-dimensional cam and the at least one switch element is arranged so as to be displaceable substantially parallel to an axis of the camshaft in order to adjust a switch point.

The disclosure provides a key device including a casing, a soft material layer, a key, and an elastic support member. The casing has a first assembly hole. The soft material layer is disposed on the casing and has a second assembly hole. The key presses the soft material layer and is disposed on the casing. The key has a key body, and the key body passes through the second assembly hole and the first assembly hole correspondingly and is exposed to the outside of the casing. The elastic support member is assembled on the key and disposed on the casing, and the elastic support member has a sliding groove. The sliding groove corresponds to the key so that the key is slidably disposed in the sliding groove. The key device of the disclosure has slidable, waterproof, and dustproof functions.

A system includes a frame and a camera coupled to the frame. The camera includes a switch having an on position and an off position. The switch coupled to the frame wherein when the switch is in an off position a portion of the switch covers the lens and the camera is disable and when the switch is in an on position the portion of switch does not cover the lens and the camera is enabled.

The invention relates to an electric switch that serves to switch on and/or off electric devices and for this purpose has a contact system in the switch housing. By means of a manual actuating element or a remotely controlled actuator, a switching operation can be effected.

A multi-directional operation switch structure seeks to improve the reliability of a product by minimizing tolerances that need to be managed by making two regions guiding the sliding movement of a slider to be formed by one holder in a switch structure in which a knob is configured on the outside of a casing, and the slider and a holder connected to the knob are inside the casing. Especially, the present disclosure can improve structural stability due to a double support structure and ensure reliability of slider movement by allowing the holder as well as the casing to withstand pressure resulting from external forces. In addition, the present disclosure can simplify a coupling structure and a support structure by configuring the slider to be coupled to the holder in a rotational manner, and the coupled slider to be limited in rotation by the casing.
