Lexmoto vixen indicator switch not working?

the indicator switch seems to be not connecting. i took apart the assembly and the screw is still in place the wires are clean so i investigated further and it appears that the ball bearing has rusted and probably so has the spring. is there a way to take apart this part of the switch clean the spring and put it back together or should i just oil and work the bearing in and out? also should the ball face the front of the bike or the rider. please help. thankyou.
