Pinitech 64 Switch Matrix Tester Review Pinitech 64 Switch Matrix Tester Review Hot

In this article I will be reviewing the Pinitech 64 Switch Matrix Tester (see Image 1).  The tester costs $47.50 for the kit and $90 assembled.  In addition you will need a wire harness kit for different types of games (the tester will work with almost all games manufactured since 1977--more information at the link above).  The un-assembled harness kits run $17.50-$18.50 and the assembled kits are $35-$36.

The board is silk-screened with the switch numbering system used by Williams on system 3-11.  In addition generic manufacturer charts are available for other systems that use a different switch numbering system.  These can be overlaid on the tester for easy switch reference.

Pinitech also maintains a switch matrix database, which currently includes 362 games.  In addition to switch numbering these also provide the switch name (see Image 2).

I purchased the kit, which comes with excellent documentation.  The assembly instructions are well written and include plenty of pictures.  One thing I always appreciate is when a couple of extra of each of the small components are included.  It's a little thing, but nothing is more frustrating than losing a diode and coming up one short.

Labels are included for the connectors with the connector number and pin one noted.  Again a small issue, but nice.

It took me about 2 hours to assemble the kit.  The process is not at all complicated, but takes a while due to the quantity of components (64 diodes, 64 switches, etc.).  In addition to the standard equipment required for soldering you will need a crimping tool for the wiring harness.  I used a Sargent 1028CT.

The usage instructions are also well written, although really not needed since everything is pretty intuitive (see Image 4).  One very nice feature is the DIP switches.  While momentary switches are great for testing functionality, once you identify a problem it's nice to be able to close the switches and free up both hands for troubleshooting.

Overall I highly recommend this product as an important part of your pinball toolkit.
