Abstract
A device for switching and controlling electrical apparatus, has a guide bearing for creating haptics indicating the position of the device. The guide bearing has one bearing part constructed as a switch housing and one bearing part constructed as an actuating element. The guide bearing has a control path formed on one of the bearing parts and a rolling-body mount constructed on the other bearing part. A rolling body is held in the rolling-body mount. A haptic spring presses the rolling body onto the control path. The structure of this device is suitable for creating haptics, without the operational reliability and service life of the guide bearing being appreciably impaired.
Claims16
A device for switching and controlling electrical apparatuses, comprising:
- a guide bearing, including:
- a switch housing that has an opening on a first end of the switch housing and a guide mandrel that is formed on and inwardly protects from a second end of the switch housing that is opposite from the first end;
- and
- an actuating element that moves in a direction towards and away from the second end of the switch housing, the actuating element having an outside end that protects through the opening on the first end and outwardly from the first end of the switch housing, an inside end that is positioned inside the switch housing, and a slide bush formed on the inside end, through which the guide mandrel of the switching housing is inserted,
- wherein the actuating element has at least one control path formed on the outside end thereof, and
- the switch housing has at least one rolling-body mount that holds at least one rolling body and at least one haptic spring pressing the at least one rolling body onto the at least one control path of the actuating element, and
- the at least one control path with engagement of the at least one rolling-body guides the movement of the actuating element in the direction towards and away from the second end of the switching housing.
