These switching elements have internal plungers and can therefore only be combined with emergency stop and mushroom pushbuttons. The PCB switching elements are placed with other components on a common printed circuit board. These can then be behind the The front panel with the actuators and light attachments. Behind the front panel, the switching elements "float" directly under the actuators on the printed circuit board, leaving plenty of room for other components. In the center channel of the switching elements, either light conductors for the use of SMT LEDs are integrated, or 3 mm THT LEDs can be installed for lighting. https://elecena.pl/product/23447731/1-20-126-414-0000-switching-element-rafix-fs-2-r-1signaling-contact-without-l 2023-05-14 https://elecena.pl/product/23447731/1-20-126-414-0000-switching-element-rafix-fs-2-r-1signaling-contact-without-l 2026-02-07
