<p>The conversion unit enables normal kitchen and wash table fittings with open outflow connections, such as spray heads or three-hole mixers, to be operated additionally by foot pressure, with normal hand operation remaining in force. It has a foot switch with electrical keys (1), one or two magnet valves (2), a reduction valve (3) and connecting parts (4). By pressure on the foot switch, the magnet valve(s) is/are opened and water is directly conducted to the outlet spray head (5). In this way, an existing kitchen fitting can selectively be operated normally by hand or foot pressure. If the unit with two valves is connected to the hot and cold water conduits, with a three-stage foot switch water at different temperatures can be delivered.</p> |
