    摘要: A cascade of safety switches includes safety switches for the monitoring of accesses of an automation system, at least one connection unit for the arrangement between two safety switches, and a terminator for the termination of the cascade of safety switches. Each safety switch has a first conductor and a second conductor. The first conductor includes conductor cores for transmitting signals and for receiving voltage. The second conductor includes conductor cores for receiving signals and for forwarding the voltage. The connection unit has a first circuit and a second circuit. The first circuit is provided for receiving the signals of a subsequent safety switch and for forwarding the signals of the subsequent safety switch to an upstream safety switch and the second circuit is provided for connecting the connection unit to a voltage source and to a conductor core for receiving the voltage of the subsequent safety switch.

    摘要: A shutter plate that is supported so as to be able to swing in both directions and covers both first and second operating parts, and a shutter mechanism that operates the shutter plate in one direction when the first operating part is to be exposed and in reverse direction when the second operating part is to be exposed are provided, wherein the shutter mechanism includes one pair of locking members for limiting or releasing the swing of the shutter plate.

    摘要: A method and apparatus for switching AC appliances and lights of residences and other automation systems through SPDT or DPDT relays connected in electrical circuit with SPDT or DPDT switch including a current sensor and/or a status sensor. The operating key of the relay and the key lever of the electric switch can each be used for operating a dedicated appliance or light, a group of appliance and lights and all appliance and/or lights including scenarios setup via the many well known two way, three way or four way light switches, by operating the switch lever or key in multi steps. The SPDT or DPDT relays are operated via RF, IR and fiber optic communicating two way signal for operating the lights and reporting statuses.
