1 brake light out....turn signal switch?

Hey all,
69 Dart. Noticed got one brake light out. Swapped sides and the bulb is good. Taillights and turn signals work (hazards dont). But the signals are getting a little twitchy sometimes. Going fast or intermittent.
Its been awhile, but I thought I remembered that the brake signal goes thru the TS switch before going down the line to the 1157s. And if the TS switch is on its way out, it could "disrupt" the brake signal. I know my lingo sux here, but Im not an electrician by any means. Im hoping you guys know what Im referring to and can verify if thats the case. If so, Ill go grab a new TS switch to see if that does the trick.
Also, could that also be why the hazards dont work? I thought they are on their own switch....but figured I should ask as long as were at it.
Thanks fellas!
