Memory (impulse) switches controlled by buttons for switching lighting from several places are a practical replacement for AC (No. 6) and cross (No. 7) switches
Latching relays, controlled by buttons from several locations can replace three-way switches or crossbar switches thanks to controlling by buttons (unlimited number, connected in parallel by 2 wires), the installation becomes easier and faster for mounting.
Relays MR-41/UNI, MR-42/UNI memorize its last state even after supply failure. During the failure, the relay will turn off and after re-energizing will automatically turn on.
