The switch supplier recently upgraded its well-established D4 switch to include an integrated RAST 2.5 connection. At the request of one of its customers in the home appliance industry, another change was made to the switch: the ability to switch special capacitor loads. This led to the development of the new D4W with an omega-shaped leaf spring. The switch offers a wiping contact system to ensure reliable switching, in particular under special conditions such as applications with capacitive loads. As with all other D4 models, the D4W can be equipped with an integrated RAST 2.5 connection system in the lid. It can be used as a ground switch in dishwashers. If water flows into the base tub due to a leak in the water cycle, the switch is activated via a float and switches the filling valve off.
