I wanted to give a review for Matt and M&M creations on his MRS Xenon tube switch. I highly recommend this as a replacement for the AS-2744-14 microswitch & wire (Xenon switch # 27). This original microswitch is NLA as far as I know.
If you are sick of bending switch wires and taking microswitches from coin doors, get one of these. I find it better than any microswitch.
Matt is a great supplier and really is concerned about producing the best possible product.
A few posted asking about installing the switch, and where it works the best. For me the location in the attached picture was the best. MRM 4 found placing his at about 7:30 was best. My pictured location would be 5:00 on the tube. For me, this 5:00 location was in the closest possible proximity to the original microswitch location. It is high enough that it doesn't false read from balls beneath it or get hit (CAUTION) by balls in the bumper area. This position for me would read both fast shots and slow shots through the tube.
You must use care when installing the switch. The reed switch inside the epoxy and casing is glass. if it takes an impact from the steel ball it could break. Make sure you keep it high enough that the ball can't hit it in the bumper area.
DO NOT expose the switch adhesive until you are sure you have found the best location for the switch on your machine. Experiment first using tape to lightly hold the switch on the outside of the tube until you find the best location. This will be where the switch is reading fast & slow shots, but is not too low to get hit with the ball or get false readings from balls in the bumper area. Also, you must place the switch far enough away from metal (the ramp, or the original microswitch metal cover if you are using it) so it does not get false readings.
Conduct your tests in active game mode, NOT switch test mode. Actual game mode strobes faster than switch test mode and will recognize your switch differently than in test mode.
All machines are a bit different. Your machine's pitch as well as slight variations in the ramp height and angle can make the ideal location on your machine different than another. You may also want to add a few inches of wire to the leads to give you more room (see picture) to try different locations without stretching the wires too much. After you have found the best location, use the alcohol pad to clean the area where you will apply the switch.
You might want to add a cap to the switch (see picture) to ensure a better detection of the switch from the MPU.
Please post a picture of your best working switch location so others might learn and have ideas of where to install their switch.
Thanks to Matt at M&M creations for making the switch!
