-## Connect swotch
+## Connect switch
 If you take a Sonoff Basic and connect a switch between pin4 (ground) and pin5 (GPIO4) of the 5 pin programming header you now have a second switch connected to the device. You can set this through the module config page as option ``09 Switch1`` or from the command line with ``gpio4 9``.
 
 If you have fewer than two relays on the module, the additional switch(es) will not show up any different than the built-in switch and will control the single relay unless you set switchtopic to something other than 0 (either 1 or a custom topic). Once this is done the built-in switch will produce ``stat/<topic>/POWER1`` while the new switch will produce ``cmnd/<switchtopic>/POWER1``

 Instead of connecting a switch, you could connect a 4-pin 2.5mm jack, with the pins wired:
 * tip pin5 (GPIO4)
 * r1 no connection
