Limit switch Type IN73

The position switches IN73 are the successful answer to an increased demand of the market. The contacts of these new series are specially designed for switching low currents.
The IN73 is a hybrid because of the sophisticated fusion of metal and plastic components: All mechanically stressed components are almost completely made of metal. The lower part of the enclosure is made of glass-fibre reinforced plastic, which also makes the IN73 economically attractive.
