Description of a computerized test stand designated for switching testing of contacts in switches used in fixed household and similar installations. Testing device has a mechanical drive, adapted for testing of key-driven (actuator) switches, and an electronic measurement system adapted for simultaneous testing of 5 switches. The stand's software enables to execute the statistical measurements of different electrical and mechanical quantities during testing of the switching ability. Current and voltage waveforms are recorded in the computer's memory and after the test they may be analysed and described in detail. The measuring system enables to designate the number, duration and arc energy of the contacts' bounces during switching on and arc duration and energy during switching the current off. Readings are then tabulated and may be presented in the graphical form.
