The Jeti Expander SW4 is an extension for Magnetic and RC Wireless switches and it’s designed for switching multiple devices simultaneously. The Jeti The 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.
If main switch is used with R3/RSW receiver/wireless switch the High Voltage Inline Regulator HVR 1W 9.5-59V must be connected to prevent damage to the R3/RSW due to high voltage input.
Now you can simultaneously turn ON/OFF your Central Box 200 and Power Main Switch or Ignition Electronic Switch SPS 20 and Receiver Voltage Regulator SBEC 40 using Jeti R3/RSW Wireless RC Switch
