DataSwitch Corporation was founded by Blaine Lowthorp and Bobbie Neff in 1980 to satisfy the market of the then-fledgling membrane switch industry.Originally a membrane switch manufacturer, DataSwitch needed the means to ensure that the switches shipped to its customers were top-quality. Mr. Lowthorp was determined that each piece shipped would have a long life and work reliably - all the time, every time - and designed equipment to test his company’s products.
The test equipment proved to be an extremely effective diagnostic resource, and our switches became recognized as highly reliable. Soon the testers themselves were in demand by DataSwitch clients for their own in-house Quality Assurance programs. Before long, Mr. Lowthorp and Ms. Neff decided to move from designing and manufacturing switches to concentrate on fulfilling the switch industry’s growing need for test equipment.

DataSwitch Continuity Testers deliver the speed and ease of use required for a production-line environment, plus the versatility and accuracy needed for engineering research. 
The DataSwitch Life Cycle Tester will test switch keys individually at a rate of one million strokes in approximately 48 hours. The switch is placed under an electrical load of 5 Milliamps DC, and is checked twice during each test cycle: once for resistance level during the 'down' stroke, and once for shorts during the 'up' stroke. Dual counters store the number of good cycles as well as the number of bad cycles (or misses). 
The DataSwitch Contact Bounce Tester measures both make and break contact bounce times on any switch with reliability and accuracy beyond that of an oscilloscope. This tester measures and displays bounce times from 0.01 milliseconds to 99.9 milliseconds. Longer bounce times are indicated by an error light.
The DataSwitch LED Tester accurately tests embedded LEDs for function and correct polarity with minimal set-up time. It will handle membrane switches with tails of up to 25 trace lines.
