A thermal imaging device, comprising: a housing (3), which comprises a front housing (31); a lens mount (1), fixedly connected to the front housing (31), a sealing gasket (2) being provided between the front housing (31) and the lens mount (1); a lens (4), threaded with the lens mount (1); and a manual lens focusing structure, comprising a focusing wheel (8) and an axial positioning structure, wherein the focusing wheel (8) and the lens (4) are connected to each other in a synchronous rotation and relative axial movement mode, and the axial positioning structure implements axial positioning on the focusing wheel (8). In the process of focusing, the lens (4) axially moves with respect to the focusing wheel (8), and the focusing wheel (8) may not move axially due to the axial positioning structure.

An electrical switch device including a switch housing having first and second compartments separated by a partition; an electrical switch assembly disposed in the second compartment; a control knob configured for seating adjacent to the first compartment, and having a user engagement portion and a plunger configured to extend from user engagement portion from the first compartment in to the second compartment via an opening in the partition separating the first and second compartments when the control knob is seated, and said plunger being configured for movable interaction with the electrical switch assembly; and a sealing member including a base portion configured for securing of the sealing member to the housing, and, a tubular portion extending from the base portion and configured to surround the plunger so as to alleviate ingress of liquid from the first compartment in to the second compartment via the opening in the partition.

Multiple position switches and specifically in-line multiple position switches where a user has definitive points of on and off switching which are used to turn multiple redundant internal circuit switches on and off. This can provide for increased reliability of switch operation. The multi-position switch is typically a five-position switch with all five positions in-line and with double or triple redundancy at each position.

A rocker switch that can include multiple redundancy at each position. Specifically, the rocker switch is a two-position rocker switch with both positions in line and with double or triple redundancy at each position. The rocker switch still provides a user with definitive snap “on” switching and the snap positions which can be used to activate multiple redundant internal circuit switches to provide for increased reliability of switch operation.

Remote control devices may control electrical loads and/or load control devices of a load control system without accessing electrical wiring. The remote control device may be mounted over a mechanical switch that is installed in a multi-gang wallbox adjacent to a second electrical device, such as another mechanical switch or an electrical receptacle. The second electrical device may be recessed with respect to the remote control device and may be brought forward towards a front surface of the adapter by loosening a first set of screws that attach a yoke of the second electrical device to the multi-gang wallbox, and tightening a second set of screws that attach the adapter to the yoke of the second electrical device. The remote control device may comprise one or more configurable attachment members for attaching the adapter to the yoke of the mechanical switch and/or to the yoke of the second electrical device.

A remote control device is provided that is configured for use in a load control system that includes one or more electrical loads. The remote control device includes a mounting structure and a control unit, and the control unit is configured to be attached to the mounting structure in a plurality of different orientations. The control unit includes a user interface, an orientation sensing circuit, and a communication circuit. The control unit is configured to determine an orientation of the control unit via the orientation sensing circuit. The control unit is also configured to translate a user input from the user interface into control data to control an electrical load of the load control system based on the orientation of the control unit and/or provide a visual indication of an amount of power delivered to the electrical load based on the orientation of the control unit.
