Guide To Wiring & Mounting 22mm BULGIN Vandal Resistant Switch, Power or Reset

Recommended Posts

I wrote the following DIY guide for casemodblog.

Manufactured from Stainless Steel, Bulgin’s extensive range of vandal resistant security switches are the most popular within the PC Modding community. They’re available from most online PC Hardware & Mod reseller and offered in three profiles – prominent, domed and low profile. The push button illuminates in the specified color. The momentary switch can be used as Reset or Power on your motherboard. The LED can be connected to your POWER or HDD activity on your motherboard. The illuminated versions are available in dot and ring LED indication and a variety of illumination colors. They offer a smaller 16mm diameter version too.

“Bulgin Started in 1923 by A.F. Bulgin OBE, the company was founded by the late Arthur Bulgin OBE, a life member of the Royal Society of Arts and of the Institute of Electrical and Electronic Engineers, and one of the six founder members of the Radio and Electronic Components Manufacturers’ Federation (RECMF). He was a man of strong principles and integrity who soon established a reputation for providing the highest level of service to customers and for secure and rewarding employment.” This has lead to the creation of what we know and love as the Bulgin switch.

The color of a Bulgin’s “water proof” insert designates the color of the LED inside.

You can insert bare wire leads in the four screw connections.

You will need two “2-pin” motherboard connections to use a Bulgin Momentary switch as your main Power or Reset

You can purchase Blue / White “2 pin” motherboard connectors, HERE

Two of the four screw connections are for powering the LED, these are located in opposing corners and the only connections labeled (+) and (-).

The other two connections for the switch, are not labeled.

Connect the Switch (On/Off) connection to the 2 pin connection on the Motherboard, labeled PWR or POWER.

You can connect the LED connection to either the 2 pin PWR LED or HDD activity connection.

Illuminated Vandal Resistant Switch LEDs come in either “RING” or “DOT” style and a variety of colors including Blue, Red, Orange, Green, UV Purple, and White. As you can see, they’re easy to install and look fantastic!
 
What about mounting 22mm vandal Resistant Switches?!

Making a mounting hole for any 22mm size switch will require a 3/4″ diameter hole saw attachment with a power drill.
 
Here is different mounting options for installing any 22mm diameter switch.

1. Your case top panel
2. Your case bezel
3. Factory 5.25 bay cover
4. Mnpctech 5.25 billet PC bay
 
I chose to install two of these Nickel plated 22mm push button switches for Power and Reset in Mnpctech 5.25 billet PC bay cover, screwed onto a factory optical drive bay cover.

Bill, those are somewhat common. PPC and Frozen sell those kinds. Some of them come with a diagram on the box, but it should be answered with my above post. I've used that kind in my Retro HTPC, Music Box, Mini HTPC, and Just A-PC.
