RELAYS WITH MECHANICAL LOCK AND COMBINED SWITCHES WITH SUCH RELAYS FOR USE IN HOUSEHOLD AUTOMATION SYSTEMS

摘要

The application describes a method and apparatus for mechanically blocking at least one pole element of a relay selected from SPST-, SPDT-, DPDT-, reversing DPDT-, multi-pole MPST- and MPDT-relays, including combining one or more combined SPDT- or DPDT -switches with SPDT or DPDT relays with mechanical interlocking, using conductive contact parts for connecting the pole parts of the relay and the switch, including on the printed circuit board to control the operation of electrical loads directly using the manual key control and remotely by applying a power pulse to the relay coil, including the CPU program to provide the manual control keys of each combined SPDT or DPDT switch connected to the connecting lines in the switch / relay node to turn on or off the group or all loads of the home automation system by optical cable, radio frequency line, wireless IR signal line and bus line.
