Claims (9)

1. Lineær aktuator (1) omfattende en elmotor (15), der via en transmission (16,17) driver en spindel (18), hvorpå der sidder en mod rotation fastholdt spindelmøtrik (19) med et aktiveringselement (2) og med mindst et fæste (3,4) for montering af aktuatoren (1), og hvor den lineære aktuator (1) yderligere omfatter et kabinet (14), et føringsrør (21) samt en elektrisk styring, hvor fæstet (3,4) er placeret i forbindelse med mindst en switch (7) og at fæstet (3,4) er arrangeret frit forskydeligt i den aksiale retning i aktuatoren (1) mellem en første og en anden position, hvor fæstet (3,4) i mindst en position aktiverer switchen (7), kendetegnet ved, at fæstet (3,4) er monteret på aktuatoren (1) med en spline-forbindelse (11,12).
2. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at fæstet (3,4) er et bagfæste (4) anbragt i aktuatorens bagende.
3. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at switchen (7) i sin aktiverede tilstand direkte eller indirekte afbryder strømmen til aktuatorens (1) motor.
4. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at switchen (7) i sin ikke-aktiverede tilstand direkte eller indirekte afbryder strømmen til aktuatorens (1) motor.
5. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at switchen (7) er placeret på et print (6) monteret i aktuatoren (1).
6. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at dele af spline-forbindelsen (11,12) er aksialt forskydelige i forhold til hinanden og danner et stop for den aksiale forskydelighed af fæstet (3,4) i mindst en retning.
7. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at det aksialt forskydelige fæste (3,4) er delvist omsluttet af et kabinet, hvilket kabinet samtidig virker som et stop for den aksiale bevægelse af fæstet (3,4) i mindst en retning.
8. Lineær aktuator (1) ifølge krav 1,kendetegnet ved, at mindst en tap (11) på fæstet (3,4), i de dele der danner spline-forbindelsen (11,12), er indrettet så den kan aktivere switchen (7).
9. Lineær aktuator (1) ifølge i et af kravene 1-8, kendetegnet ved, at switchen (7) er monteret i en udsparing (10) på aktuatoren (1) i forbindelse med spline-forbindelsen (11,12) på fæstet (3,4).
