Push-button switch assembly with means for indicating a switch status

A push-button switch assembly with means for indicating a switch status, comprising:

• an actuation head configured to actuate the push-button switch assembly, the actuation head having a disc-shaped upper part and a tubular lower part;
• a sleeve-type push-button guide which is coupled to the actuation head such that, in relation to a longitudinal axis of the push-button switch assembly, the upper part is arranged above the push-button guide and the lower part surrounds the push-button guide;
• a sleeve-type locking unit configured to determine a switch status of the push-button switch assembly, the sleeve-type locking unit being arranged within the push-button guide in relation to the longitudinal axis and being transferrable between a first and a second locking state by the actuation head, the locking unit having a plunger sleeve and an annular detent catch coupled to the plunger sleeve, which delimit a central through-opening through the locking unit perpendicular to and along the longitudinal axis in a predetermined manner, the detent catch comprising a multipiece design and a first detent catch element and a second detent catch element which are preloaded by two spring elements which, in relation to the longitudinal axis, push the detent catch elements outward;
• and
• a light guide configured to guide light, which light guide is coupled to the actuation head such that, in relation to the longitudinal axis, at least portions of the light guide are arranged within the actuation head and within the push-button guide, the light guide, in relation to the longitudinal axis, extending with a top end in a predetermined position through the actuation head and with a bottom end, extending through the through-opening of the locking unit such that the push-button switch assembly is illuminatable in a predetermined manner by a light beam that is couplable into the light guide at the bottom end.
