Automated testing of hybrid actuator

摘要

There is provided a testing apparatus (200) for a hybrid indicator lens and potentiometer actuator (100). The hybrid actuator (100) serves both as a knob for a potentiometer (120) and as a lens to convey light from an indicator arrangement (110). The test apparatus (200) includes a rotatable test head (204) having a light sensing means (210) and an engaging portion (202). The engaging portion (202) engages with a corresponding receiving recess (102) provided on a head portion (114) of said hybrid actuator (100) and thereby aligns the light sensing means (210) with the hybrid actuator (100). The testing apparatus (200) performs automated tests which include rotation of the hybrid actuator (100), and therefore the potentiometer (120) to a range of test settings and inspection of the functionality of the indicator lens arrangement (110). <IMAGE>
