Claims
- 1. An electric control device comprising:
- a closeable housing having a housing opening;
- a control shaft insertable into said housing opening;
- at least one adjustable control element enclosed in said housing to be driven by manipulation of said control shaft, said at least one adjustable control element having an engagement opening for receiving the control shaft;
- means for radially positioning said control element within said housing so that the engagement opening is aligned with the housing opening to receive the control shaft there through;
- quick connection means secured to said control shaft for axially securing said control shaft relative to said at least one adjustable control element, said quick connection means permitting insertion at said control shaft into said at least one adjustable control element through said housing and inhabiting retraction therefrom, wherein said positioning means includes radial guidance means connected to the casing for positioning said at least one adjustable control element.
- 2. The device according to claim 1, wherein the control shaft and the adjustable control element engage along a circumference of the control shaft.
- 3. The device according to claim 2, wherein the control shaft adjusts the adjustable control element by substantially mating engagement of the profile of the control shaft with the engagement opening of the adjustable control element.
- 4. The device according to claim 1, wherein the quick connection means is an automatic, positively acting snap connection.
- 5. The device according to claim 1, further comprising an annular locking element having an opening and secured to said housing so that the opening is aligned with the housing opening to receive said control shaft therethrough.
- 6. The device according to claim 5, wherein the locking element is axially moveable relative to at least one adjustable control element and has means for locking rotation of the shaft relative to the casing, which locking means can be unlocked by said relative axial movement.
- 7. An electrical control device comprising:
- a control shaft having a circumferential recess;
- at least one adjustable control element for controlling electric equipment functions, adjusted by manipulation of said control shaft;
- a housing for said at least one adjustable control element providing an aperture for passage of said control shaft therethrough, wherein the control shaft is insertable through said aperture and has a spring clip secured to the control shaft, said spring clip having a clamping portion secured to said circumferential recess of the shaft, a locking portion bent away in barb-like manner from the shaft and a radially projecting stop portion, said locking portion axially securing said shaft relative to said adjustable control element in said stop portion limiting the depth of insertion of the control shaft into said adjustable control element.
- 8. The device according to claim 7, wherein said portion of the spring clip is strip-like.
- 9. An electric control device comprising:
- a closeable housing having a housing opening;
- a control shaft insertable into said housing opening;
- at least one adjustable control element enclosed in said housing to be driven by manipulation of said control shaft, said at least one adjustable control element having an engagement opening for receiving the control shaft;
- means for radially positioning said control element within said housing so that the engagement opening is aligned with the housing opening to receive the control shaft therethrough; and
- quick connection means secured to said control shaft for axially securing said control shaft relative to said at least one adjustable control element, said quick connection means permitting insertion of said control shaft into said at least one adjustable control element through said housing and inhibiting retraction therefrom, wherein the control shaft has a recess and the quick connection means is a spring clip secured in said recess of the control shaft.
