Space Brain: the nuclear detonator.
The Beta Cloud: the same control fires the laser canon (the labels say "LASER" and "FIRE").
In Life Support Section (a minimally altered Weapons Section) in Seed Of Destruction
Dorzak: it also appears in the background in a Technical lab (in the centre of this shot, in front of the door).
Dorzak: note the radiation symbol.
Brian The Brain: it is in the Swift passenger section (in the foreground of this shot).
The Mark Of Archanon in Medical... the radiation symbol is clearly visible.
The timing device is also seen in Eagle 4 in The Immunity Syndrome
The Exiles: the laser control in the Research station.
Maya is turning the dial in this shot from The Beta Cloud. Instead of aiming the laser control (here Tony is using the Eagle remote control for that), Maya is controlling the sensors so she can read the coordinates of the cloud.
The Dorcons: on Koenig's desk in Command Centre.
The same control is also seen in The Seance Spectre controlling an Eagle laser turret (it has "Laser Control" written on the side).
In The A B Chrysalis a trigger is used for the Eagle turret.
