Definitions
- the invention relates to a protective cap made of elastic Material for a switchgear with a rotatable handle.
- IP 68 In order to achieve the desired degree of protection, e.g. IP 68, can be achieved the complete covering of the front ring of the rotary switch required.
- the invention is therefore based on the object of a protective cap of the above type to create the inexpensive producible and in particular for sealing, e.g. a toggle handle, suitable as a handle for an electric rotary switch is.
- the protective cap one inner space of the shape has that the handle in the space occupied when it is actuated, without any reset torque is freely movable through the protective cap.
- the protective cap deformed so far that the handle around her Switching angle, possibly rotated in both directions can be.
- the protective cap forms after you let go back to their starting position. It is for both latching than suitable for groping gags.
- the switching device is a rotary switch that has a collar and if the protective cap has an area that can be put over the collar having.
- This embodiment enables compliance high sealing requirements, since the protective cap after Slip on the collar or the front ring of the rotary switch when it is fastened by means of a holder between a front plate and a front plate seal becomes. In this way, the protection class in "IP 68" applicable requirements.
- FIG. 1 shows a protective cap 1 according to the invention, which is made of elastic Material consists of two recessed grips 2.
- the inner free space of the protective cap 1 is shaped in accordance with FIG. that the handle of the knob of a rotary switch in the space occupied upon actuation without a reset torque is freely movable through the protective cap 1.
- the protective cap 1 is deformed to the extent that the handle is rotated by the switching angle described above can be.
- the protective cap forms after releasing 1 back to its starting position.
- the protective cap 1 is over with its area 5 the collar 6 of the rotary switch 3 slipped, with which the above Tightness requirements are met according to the task.
