here is a working solution; since I use a European keyboard I used a letter "o" for testing – you'll have to swap it with "equal_sign" for yours!

{  "description": "Will exchange principal with secondary key 'expression' …",
   "manipulators":
   [ {
           "type": "basic",
           "from": { "key_code": "o",
                     "modifiers": {
                        "mandatory": ["left_shift"],
                         "optional": ["any"] }
                   },
             "to": [ { "key_code": "o" } ]
     },
     {
             "type": "basic",
             "from": { "key_code": "o",
                       "modifiers": { "optional": ["any"] }
                     },
             "to": [ { "key_code": "o",
                       "modifiers": "left_shift" } ] 
     }
   ]
}
