Hey guys can I use any push on push off button or toggle switch for my sim? Providing they are not illuminated are there any restrictions on what toggle and pushbuttons I can usitise? Momentary switches has me stumped a bit, if I use a momentary switch for say switching the bottom eicas screen (767), will the screen only show a change whilst the button is pressed( hence momentary) and then revert when the button is released? Or will the screen change over when the buttons pressed and you need to press it again to change the screen back? Same again with say a fuel pump etc? Thanks again for you advice :)
