A valve controller includes a housing defining an interior volume, and a transmission assembly at least partially disposed in the interior volume of the housing. The transmission assembly includes a shaft coupled to a cam sub-assembly, which includes a first side and a second side opposite the first side, a first cam, and a second cam coupled to the first cam. Each of the first and second cams includes a bore arranged to receive the shaft and a lobe. The lobe of the first cam and the lobe of the second cam being at least partially coplanar. A first switch and a second switch are disposed in the interior volume of the housing and adjacent to the transmission assembly. The lobe of the first cam is arranged to activate the first switch and the lobe of the second cam is arranged to activate the second switch.

An apparatus for carrying out inputs in an input capturing unit that can be coupled to the apparatus. An operating device has a receiving part and an operating element that is rotatably mounted on the receiving part. The operating element can be rotated by a finger to effect an input. A torque for the rotation of the control element can be adjusted by way of a controllable braking device. In addition, the control element has at least two actuating zones. The resistance to movement for the movability of the operating element can be adjusted depending on from which actuation zone the operating element is actuated and/or which actuation zone was previously activated.

In one example, a rotary knob switch includes: a knob head; a fixing mount disposed below the knob head and configured to allow at least a portion of the bottom of the knob head to pass through it; cam located at the bottom of the fixing mount and to be mated with the bottom of the knob head, a side of the cam forming at least one protruding control curved surface; and a slider, said slider being coaxial with the cam, ramp with different heights being provided along edge of the slider, wherein, when the cam rotates, the control curved surface of the cam presses the ramp of the slider, such that the slider slides along axial direction towards the bottom of the rotary knob switch, the knob head comprises an indicator block, the lower part of the indicator block is provided with an axial light guide column.

A control device may be configured to control one or more electrical loads in a load control system. The control device may be a wall-mounted device such as dimmer switch, a remote control device, or a retrofit remote control device. The control device may include a gesture-based user interface for applying advanced control over the one or more electrical loads. The types of control may include absolute and relative control, intensity and color control, preset, zone, or operational mode selection, etc. Feedback may be provided on the control device regarding a status of the one or more electrical loads or the control device.

An operation panel is provided on a vertical surface of an electrical appliance. The operation panel is provided with an operation surface having an uneven structure. A thin switch is provided in a recess portion of the operation surface.

A switched power receptacle that can be programmed to provide power for a user-selected duration in a user-selected cycle. The invention can be plugged into a conventional receptacle, extension cord, or other source of power. One or more user inputs and displays are provided so that the user can program the cycle for switching on the power (once every 2 days, once every 7 days, etc.). One or more user inputs are provided so that the user can select the duration of activation for each cycle (1 hour, 3 hours, etc.). Status indicators are preferably provided so that the user can easily monitor the operation of the device.
