+# Trident dual power switch
+![Dual switch](Images/DualSwitch.jpg)
+
+This is a simple mod to allow mounting two switches along side the filtered inlet, rather than one.  
+The intention is to wire this so that the Raspberry Pi remains powered, even when the rest of the system is off
+
+## Hardware
+This mod only works with the filtered inlet from the sourcing guide, not any of the all-in-one options.  
+It should work with any switch that works in the stock skirt, you just need 2 of them now.
