Push Button and Keyboard Test

Automatic Mechanical and Electrical Tests Detect Push Button and Keyboard Defects

Push button and keyboard test is critical to detect faults that might go uncovered after their commercialization. Push buttons and keyboards have a wide range of applications from consumer or industrial equipment control on devices and consoles, to simple buttons on electrical panels. Mechanical and electrical response for push buttons and keyboards are important to be measured to ensure that the devices operate the way they were designed.

Many parameters can be measured to detect defects and they depend on the product under investigation. For example, a stiff button can be difficult to operate, a key might not respond when it is pressed or the PCB might not send the signal to the controller.

Key challenges in testing push buttons and keyboards


Detecting push button and keyboard defects might involve several test types such as tactile and electronic actuation, ergonomy, communication, and more. All these tests do not always occur simultaneously and they are often measured separately and manually, harming efficiency and production costs. This especially affects high-volume manufacturing environments where high quality, controlled costs, and fast time to market are fundamental elements to win over the competition.

Having automatic test equipment that detects defects by combining both mechanical tests and electrical tests, on a single automatic tester, improves measurement accuracy while reducing testing operating costs, scraps and release time.

SPEA has addressed push buttons and keyboard manufacturers’ challenges by designing automatic test equipment capable of performing these functional tests in an integrated way.

Robotic actuators and automatic tools boost push button and keyboard testing


High-performance robotic actuators act like human fingers, simulating real touch gestures on the keys. By pressing every key at programmed force and controlled speed, the tester verifies the correct key working on the entire surface.

In addition to that, high-performance visual units verify the correct positioning of each key on the keyboard while contacting probes test the electrical connections.

SPEA automatic test equipment for push button and keyboard test can accommodate several testing tools to fit the specific testing requirements, including:

  • Force application, stroke and press tests
  • Character test
  • Communication ports test
  • WIFI connections test
  • Flashing

Linear motion technology for accurate push button and keyboard test


The SPEA robotic architecture is based on full linear motion technology with absolute linear encoders, which ensures:

  • Extreme precision and accuracy of the actuator positioning
  • No need for homing procedures, since the system can self-monitor the position of the actuator at any moment, with sub-micron resolution
  • No performance drift over time, no influence brought by thermal expansion
  • Automatic calibration, thanks to built-in axes calibrators


Increasing throughput and product quality while lowering production testing costs makes it challenging for manufacturers to meet these requirements. SPEA automatic test equipment that combines mechanical tests and electrical tests, on a single automatic tester, can help the industry overcome its challenges and meet the market demands.
