SWITCHING MEMBER HAVING CONTACTLESS INDICATOR

An electric switch device having a fixed base body (10) and an actuator key (7) that is arranged movably relative to said base body (10). A non-galvanically coupled indicator display (1) is arranged within the actuator key (7). Within the base body (10) a radiation source (4), preferably a light emitting diode (18) is provided for, which is actuated by coded pulses, and is coupled non-galvanically with a means (3) for converting radiation into electric signals, preferably with a photocell (19) that is arranged within the actuator key (7). Output voltage generated by said photocell (19) is applied both to a rectifier and to a processor unit (2) that are both arranged within the actuator key (7). The indicator display (1), preferably liquid crystal display (LCD) is activated by the processor unit (2) while the rectifier provides supply voltage both for the processor unit (2) and for the indicator display (1). Thus, the actuator key (7) is merely non-galvanically coupled with the fixed base body (10) and a large variety of symbols such as geometric patterns, characters and the like according to coded pulses imposed may be visually displayed by using one and the same indicator display (1).
