Modular selection button

A modular selection button for actuating contact elements comprising

• 1 a housing (6);
• 2 a rotating handle (2);
• 3 a transmission member (4′;
• 5′) which is non-rotatably coupled to the handle (2) and supported in the housing (6) and carries an axially acting switching cam;
• 4 stop means including stops which are fixed relative to the housing (6) and counterstops which can be rotated using the handle (2) and which serve for limiting the angle of rotation of the handle (2);
• 5 at least one switch plunger (81) which is supported in the housing (6) in a manner that it is non-rotatable as well as axially movable against spring means (82) and which cooperates frontward with the switching cam via a symmetrically formed end face (86), the switching cam and the end face (86) being designed in such a manner that the transmission member (4′;
• 5′) latches onto the switch plunger (81) when a specific angle of rotation with respect to the resting position is reached;
• wherein
• 2.1 the handle is a key actuator (2);
• 3.1 the transmission member (4′;
• 5′) has a disk-shaped design and carries axially projecting switching cam elements (42;
• 52) on the rear side (41;
• 51),
• 4.1 when working with a latching rotated position with respect to the resting position, the stop means which act for the specific direction are:
• 4.1.2.1 with key (21) being releasable in the rotated position:
• third stop means including a third stop (28) which is fixed with respect to the housing (6) and a third counterstop (48′;
• 58′) on the transmission member (4′;
• 5′),
• 4.1.2.2 on the other hand, with key (21) being retained in the rotated position:
• fourth stop means including a first stop slide (91) to be inserted, in a latchable manner from behind, into the housing (6) which is open on the rear side and a fourth counterstop (47;
• 57) on the transmission member (4′;
• 5′), the angular distance in the direction of rotation between the decisive first stop face (94) of the first stop slide (91) and the fourth counsterstop (47;
• 57) being somewhat smaller than the angular distance between the third stop means (28, 48′;
• 28, 58′);
• 4.2 when working with a momentary-contact rotated position with respect to the resting position, the stop means which act for the specific direction are:
• fifth stop means including a second stop slide (92) which, in lieu of the first stop slide (91), is to be inserted into the housing (6) in a latchable manner and the fourth counterstop (47;
• 57) on the transmission member (4′;
• 5′), the decisive second stop face (95) of the second stop slide (92) being positioned before the first stop face (94) of the first stop slide (91) in the direction of rotation.
