A safety switch with a lock-out device comprises a switching unit (2) adapted to be anchored to a fixed part of a structure and provided with switching means adapted to be operatively connected with at least the power supply circuit of the plant to be controlled for the opening/closing thereof, an operating unit (3) adapted to be anchored to a movable part of the structure and having actuating means (5) adapted to interact with the switching means upon the closing of the movable part on the fixed part to enable the closing of the power supply circuit, a lock-out device (16) associated with the switching unit (2) and having a guard (17) movable between an inactive position adapted to allow the interaction between the switching means and the actuating means (5) and an active position wherein the interaction is avoided. The switching means and the actuating means (5) are of the electronic type and are respectively associated with a first communication element (6) and a second communication element (7) adapted to remote communicating therebetween by means of a presence signal and to allow the switching means to discriminate the presence of the operating unit (3) close to the switching unit (2). The movable guard (17) comprises a shielding element (20) adapted to interpose itself between the communication elements (6, 7) when the guard (17) is into the active position to avoid the transmission of the signal and the closing of the switching means.

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.

An illumination system and method are disclosed for maintaining a consistent change in illumination value among a group of illumination devices whenever a change command is manually sent from a keypad to those illumination devices. The consistent change results from maintaining a common start illumination value among not only the group, but also the keypad which controls the group. From the start illumination value, the keypad can then compute an end illumination value depending upon the amount of time that an increase or decrease in illumination value button is depressed and held. Since the change command can arrive at different illumination devices within the group depending upon where each illumination device is geographically located, a masking time is reserved after the button is released so that enough time is allocated for each of the illumination devices within that group to arrive at a common end illumination value.

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.

A multi-way circuit having a plurality of base modules may be used in multi-way schemes for lighting control devices. The multi-way circuit may operate with a controller and the base modules of a lighting control system to provide a fully functional, multi-way toggle circuit, even when the switches installed in the base module are not paired or in their off modes. The multi-way toggle circuit can be defined as follows: if any button in the circuit is pressed (indicating a desire to change the load state), then the load toggles its state between on and off.

A circuit breaker is for protecting a low-voltage circuit when current or current-time limits are exceeded in the low-voltage circuit. The circuit breaker includes an electronic trip unit which initiates an interruption or reduction of the current flow in the low-voltage circuit when first current or current-time limits are exceeded, and second current or current-time limits stored in the electronic trip unit, which are characterized by lower current limits or lower current-time limits, the second limits being activatable by an initiated switchover. A communication unit connected to the electronic trip unit is provided, which enables wireless communication, and the circuit breaker is designed such that when a wireless communication signal is received that exceeds a field strength value, the second limits are activated.

The present invention provides a switch which allows a communication module to be made waterproof while maintaining a switch function. A wireless switch device which functions as a rocker switch includes a cover member and an elastic waterproof member both of which seal an opening of a casing member in a state in which a wireless switch module is housed in the casing member. The wireless switch device further includes a seesaw-shaped member which is arranged on an outer side of the cover member and the waterproof member which outer side is opposite to a side on which the wireless switch module is sealed with the cover member and the waterproof member.

A remote controlled light switch cover assembly is described for converting a standard rocker switch into a remote controlled switch. In one embodiment, a method is described, performed by the remote controlled light switch cover, comprising receiving a wireless signal to actuate the standard rocker switch, activating an electric motor that causes a wiper to move along a surface of the standard rocker switch, detecting when the wiper has actuated the standard rocker switch, causing the electric motor to rotate in a reverse direction from the first direction, which causes the wiper to move back towards a valley of the standard rocker switch, detecting when the wiper is positioned over the valley, and in response to detecting when the wiper is positioned over the valley, causing the electric motor to stop rotating, causing the wiper to remain positioned over the valley.
