High-quality actuating element. It allows the space-saving layout of keypads whilst also providing a sufficiently large actuation area. Installation: Workshop-friendly one-hand assembly, fastened using supplied hex nuts. The command devices can be stacked adjacently The push button guarantees a visible indication of the switch position when using standard elements with latching mechanisms (switches). For all other switch element types, the button returns to its initial position after every actuation. Bulbs are replaced from the front (removal of the button body) or directly on the switching element.
