The indicators in the WA46 series are distinguished by an illuminated display area of 46 x46 mm. The design is matched to the buttons in the WT40 series. There is a variety of symbol slides available in stock. The indicator light is uniformly illuminated with a flat and long-lasting LED module. The operation is carried out with a 24V power supply (EN 50155). Multiple displays and audible feedback can be configured. The indicators are available in different colours, as well as custom designs. When switched off, the display symbol can be optionally hidden (known as the vanishing effect).
