Tomb Raider III. For information about the key found in Tomb Raider II, see Detonator Key.
The Detonator Switch is an item found in the Nevada Desert level in Tomb Raider III.
It is used to blow up a rocky wall with dynamite. The Detonator Switch is inserted to a detonator, and then Lara uses the device to set off some explosives nearby. This makes it possible to travel further into the desert all the way to the prison area.
The Detonator Switch is hidden into an elevator shaft.
