Universal testing machines for testing electronic components and parts.
For testing fasteners, the testing machine can be equipped with grips and a T-slot plate for flexible positioning and axial alignment of the specimen. An integrated digital multimeter is used to measure resistance during tensile strength testing.
In another test setup, a shear fixture can be used to test contact elements, such as switching contacts of circuit breakers from the electrical industry, to ensure safety when handling electrical components. The shear tests are used to determine whether the soldered contacts between the switching contact and the component can withstand the stresses in practice. For this purpose, the component to be tested is clamped in a specially developed shear fixture and subjected to a steadily increasing shear force until the switching contact shears off.
For the testing of electrical switches and pushbuttons, special devices are used to check the force and the distance required to actuate and release the pushbuttons or to operate the switches.
If necessary, several different load cells can be mounted simultaneously to apply different force ranges.
The force is checked via these load cells or via the voltage of a probe adapted to them.
Test leads for the switching signal are connected to the switch/pushbutton so that there is immediate feedback of the signal in connection with the test process.
