Azure IOT HUB routing

My IOT hub receives telemetry message from kepserver in the format

{
"CNC-Model_Performance.CNC-Model_KPI-Prameters.Station_Idle":false,
"CNC-Model_Performance.CNC-Model_KPI-Prameters.Ideal_Cycle_time":120,
"CNC-Model_Parameters.CNC-Model_Prameters-Alarms.Alarms.SPINDLE MPCB TRIPPED":false,
"CNC-Model_Parameters.CNC-Model_Prameters-Alarms.Parameters.Coolant Temperature":0,
"CNC-Model_Parameters.CNC-Model_Prameters-Alarms.Alarms.Hydraulic Motor Current is High":false,
"CNC-Model_Parameters.CNC-Model_Prameters-Alarms.Parameters.Incoming Voltage":0
}

I need to route the data to a service bus if the SPINDLE MPCB TRIPPED is true or Hydraulic Motor current is High is true.
I am not able to put the correct route syntax as the tags has dot and spaces present and i am not able to override them .
So putting a condition like this $body.CNC-Model_Parameters.CNC-Model_Prameters-Alarms.Alarms.SPINDLE MPCB TRIPPED = true is not working . Any ideas ?
