B886 "Simon" Life Cycle & Switch Bounce Test System

The B886 Simon System has been designed for life cycle and fatigue testing of switches, membrane switches, keyboards and keypads. It system contains all the components needed to life and fatigue test a wide range of components (Control Unit, test fixture, power supply, pneumatic cylinder & Hoses, silicone test probe, USB lead, Windows software and instruction manual).

 

How easy is it to use?

Simply decide on the force required, enter the resistance values, the number of cycles and product name then push start. There are lots of other things that you can set or adjust but for many tests the default values that Banair have already entered for you will be fine. When the test is completed the results will be stored in an Access database and you can print out a test certificate.

Now, simply put the product in the jig and place the probe over the switch to be tested.

How long will the test take?

The typical membrane specification calls for 1 million operations. If you set the system for 4 cycles per second then this would take just under 3 days.(4 cycles x 60 seconds x 60 minutes x 24 hours x 3 days = 1,036,800 cycles) You may need to adjust the cycle time depending on your requirements. The test time for 1 C/S would be just under 12 days. (Testing Specification ASTM F1578-01, ASTM F1578-07, ASTM F1578-96)

 

What else do I need to get started?

1. A PC or laptop running Windows and a free USB socket. Microsoft Office will help you analyse and print your results but you can perform standard tests without this.

2. An air supply (Max 6 bar).

3. A product to test.

Everything else is included for you to start testing straight away.

 

Why is it called "Simon"?

We like to give our equipment names as you might have noticed, why do we do this, well, as you will find out, they will soon become part of your team, just like a new work colleague.

Switch Bounce Testing

Nearly all switches will generate some "bounce" when they are operated (switched). Every time they are operated, they will actually open and close their contacts several times before they settling down to their new position. For normal switches, this can last from as little as a fraction of a millisecond (ms), to as long as several milliseconds. Only very high quality switches generate little or no bounce. This switch bounce is not usually a problem if you are merely turning on something simple like a light, but if you are working with more sensitive things like logic devices, all these extra bounces can create havoc. An example of a problem would be that if every time you pressed a button to increment a counter you actually added several counts to the total.

How do I set up the system?

Connect the switch to the connector on the front of the tester. Select the required resistance range.

Push the switch and the tester will display the resistance. This will confirm the switch resistance and allow you to determine the bounce threshold.

Once you know the resistance when the switch is closed then you can determine the bounce threshold. Enter this as “Resistance Spec Ohms”. You can also enter the serial number, Part Number and customer details to be saved in the results and printed on certificates.

 

How do I carry out the test?

Click Keybounce and then push the switch and release it. A graph will then appear of the screen and the rise and fall bounce times will be measured and displayed.

The results can then be stored in an Access database. The system can also be supplied with the ability to save the results to an Excel spreadsheet.

SAVE TIME - Operate up to 8 cylinders at the same time!

The standard B886 Simon system has a single switch input that measures the resistance of the switch, there is also the option of up to 8 digital inputs for systems where multiple fingers are required but without the need of resistance measurement. When using this option all of the cylinders / fingers will operate at the same time via a manifold .
