I'v just checked against the XML file and cofirm that your Rotor Brake control parameters are correct😉
ie, I took here a snippet from the VNAV part : left click = (386 + 100) + 1 = 38601
<!-- 386 - VNAV Switch Collins ############################# -->

386 100 * (>L:SwitchID, number)
(M:Event) 'LeftSingle' scmp 0 ==
if{
(L:SwitchID, number) 1 + (>L:SwitchID, number)
}
(M:Event) 'RightSingle' scmp 0 ==
if{
(L:SwitchID, number) 2 + (>L:SwitchID, number)
}
(...)
the advatage here is that you get also the name and type of the lvar that receives the actual state of the switch L:switch_386_73X, number
