Eels must be provided with such facilities also in In these cases, an absolutely joint-tight and reliably disinfectable solution The design of the handpieces is extremely urgent.

The invention has set itself the task of a handpiece for switching and operating devices to create, which against Hospitalism Sure 1st · There is still the task of having it is easy to disinfect «Furthermore, the task should be that disinfection can be done several times and after one For a certain time, the cover that closes the parts can also be removed is and can be replaced by a new one · Hur in this way it is possible against hospitalism with a certain Proceed to success.

There is also the task of ensuring that the switching and operating devices can be upgraded, i.e. «that the * · £ · are in use located can be exchanged without affecting the systems need to be changed

From · * auoh there is still the · task of designing the device in such a way that that it works not only as a handpiece, but also as a foot dressing can be trained

The invention solves the problem posed by a Handpiece for switching and operating devices is created, which with one on the housing and on the operating elements and supply line parts. dlohteehüllenden envelope », in the form of a Foil, is coated *

This film is drawn up so tightly that the Sehalttr as

part given

You can also form the supply line β ο that the Plug is molded on the cable at the end point, so that there is also no joint formation there

The most practical switching elements used on the handpiece are pushbutton switches that have relatively short switching paths and thus allow actuation without the foil covering

bW regulation devices ζ · Β · for sound et ärkeeins distribution using the most expedient en stages pushbutton switch, allowing to switch the three or four stages ·

However, regulating devices can just as well be used for this purpose provide, which are designed as rocker potentiometers, two adjacent pushbuttons rocker-shaped connected via a bar and thus a volume control through the slide can be done through

However, there is also the possibility of sliding potentiometers instead of the regulating devices indicated so far to be used, which protrude with their knots, for example, on the side of the housing and with the fingers through and slide open can be operated

The invention can also be realized that a Process for the production of the handpiece is used in which a split housing for the handpiece is used finds, which is designed as a main part with what can be closed with a lid. «The main part is used for

009832/0756

would take the control elements and the supply line parts is the main part of the case before assembling the parts! joint-tight overflow or designed so joint-tight as a whole, so that after assembly of the "^ hurry a corner-shaped part jointless can be glued or welded on

According to the invention, the handpiece can also be designed so that the controls and switches are in the housing are arranged so that the housing made of a deformable material at the points where the pushbuttons are designed like a membrane, so that the buttons can be operated without joints thanks to the shape of the housing

This form of training can in the manufacturing process β ear be expedient and enable production to be cheaper

However, one can also proceed in such a way that the basic housing part, i.e. the ^x 'part, which accommodates the control elements with the supply line parts and the plug-in devices on the linden tree, forms a joint-free, closed part which has membrane-like points above the buttons in the housing, with the Provided that the transition edge to the end cover is designed in such a way that joint-free welding or gluing is possible, in such a way that a hand remains on the halves after the connection, after the connection, joint-free, smooth, flat tbschleiX- etc. can be polished · In this way ■ loh can produce a “very light and cost-saving housing that meets all the requirements of freedom of vision”
