You will need to drill a hole in the front panel of the DGCIII for the switch, and then move the wires over from the rocker switch section to the double pole single throw switch as shown in the above image.<\/p>\n\n\n\n<p>Due to space limitations inside the DGCIII the DPST switch will need to be mounted sideways.&nbsp; In this case the new DPST switch will turn the DGCIII on and off, and the original power switch will still control the ion gauge selection which is typically UHV. Make sure that the DPST front panel switch can handle 5 amps @120 VAC or more. A typical DPST switch is shown below.<\/p>\n\n\n\n<figure class=\"wp-block-image size-medium\"><a
