Abstract
The invention relates to a finger tester probe including a probe element for electrically contacting a contact point of a circuit board under test, an actuator including a permanently premagnetized core and a solenoid element. The solenoid element is shiftingly arranged on the permanently premagnetized core and is mechanically connected to the probe element. Upon being energized, the solenoid element is moved together with the probe element. Since in accordance with the invention a movable part of the actuator is not mechanically connected to a fixed part of the actuator, the test probe which is attached to the movable part is able to bring the probe element into contact with a contact point of a circuit board under test at high speed.
