Small in format, but great in its potentials: The buttons and indicators from Style 28 along with many matching components, make the scope of design almost unlimited. Whether it is an arranged car fixture, or a space-saving landing fixture with a minimalist design the choice of elements and materials determine the look. While the Armour Button type PT 28 is especially durable, the Electronic Button type ET 28 also serves as a basic element for large-format variants, which range in various shapes and material combinations.

This button is not suitable for use as an alarm/door open button. The reason being: by operation of the button the signal is only set for about 1 second. As a respective alternative for an alarm/door open button we recommend: MT 28, design PT 28.
