Abstract
An actuator is disclosed for actuating a safety switch. In at least one embodiment, the actuator includes a fixing element, an actuating element, and a connection arrangement for connecting the elements. A technical method is disclosed which proposes a universally applicable and low-cost activator. To this end, in at least one embodiment, the connection arrangement is implemented with at least one elastic element, which is pretensioned by way of at least one pretensioning element. Due in particular to the internal mounting of the pretensioning element inside the elastic element, a very simple and robust structure of the connection arrangement is achieved.
Claims19
An actuator for actuating a safety switch, said actuator comprising:
- a fixing element;
- an actuating element;
- and
- a connection arrangement connected directly to a surface of the fixing element at a first end of the connection arrangement and connected to the actuating element at a second end of the connection arrangement, the connection arrangement including at least one resilient element, pretensioned by way of at least one pretensioning element, to connect the fixing element to the actuating element, wherein each component of the connection arrangement is directly connected to the surface of the fixing element.
An actuator for actuating a safety switch, said actuator comprising:
- a fixing element;
- an actuating element;
- and
- means for connecting the fixing element to the actuating element, the means for connecting including at least one resilient element, pretensioned by way of at least one pretensioning element, for connecting the fixing element to the actuating element at opposing ends of the connecting means, wherein the pretensioning element is directly connected to each of the fixing element and the actuating element.
An actuator for actuating a safety switch, said actuator comprising:
- a fixing element;
- an actuating element;
- and
- means for absorbing applications of force on the actuating element at least one of along and perpendicularly with respect to an actuating direction, the means for absorbing including at least one resilient element, pretensioned by way of at least one pretensioning element, the means for absorbing being connected to the fixing element and to the actuating element at opposing ends of the absorbing means, wherein the pretensioning element is directly connected to the fixing element.
