2nd switch in mission 6-a

[Sariel37]

I found the first switch on the 2nd floor which unlocked the first set of blast doors but for the life of me cannot find the 2nd.

did you go down the 2nd ramp? cant remember but think its over that way

yeah went up the 2nd floor went down the ramp on the other side hit the switch that was at the fork which took you back to the main room. Now says there is a 2nd switch but all the switches are hit except for 1 back in the start that i can hit multiple times to lock/unlock the door with the chest at the start

Figured it out the door you already used to open the first boss fight of the area
