Global communications Power switch
The power switch works by switching between the two LNB's by dropping power to the switch
on most receivers this in turn is achieved by double pressing the standby button although you may need to configure this on some receivers
so when the receiver is on and sending an LNB Voltage and you're receiving signal from LNB "A" simply switch off the power (standby) to the LNB then back on to select LNB "B"
this is a cheaper alternative to using a DiSEqC switch
the switch is designed to be mounted behind your satellite dish and kept in place with a single cable tie
