The Jeti Expander SW4 is an extension for magnetic and RC wireless switches and is designed for switching multiple devices on/off simultaneously. The Jeti Expander SW4 allows you to combine the switching duties so that several devices can be controlled using one only element. Furthermore, some outputs are optically isolated to prevent interference. This makes it is possible to isolate control of devices which may be sensitive to electric interference.
Now you can simultaneously turn ON/OFF your Central Box 200 and Power Main Switch using Jeti R3/RSW Wireless RC Switch.
