The E-series pushbuttons are available in round (ER50) and square (EQ50) designs in a size of 40 mm. They are mounted on matching carrier boards, which are designed for complete pushbutton arrangements in rectangular or strip form. Each position on the carrier board can be equipped with either a standard pushbutton, a key switch, or an alarm pushbutton.

The E pushbutton series features an elegant black design with an anti-fingerprint coating.

The push buttons are fastened with screws, which also establish the electrical contact. After cutting the carrier board to size, all that is required is to connect the supply voltage and the call. The connection can be made using screw terminals or ribbon cables. An acoustic acknowledgment is provided either centrally via the carrier board or directly via a push button.

The E-push buttons have a wide range of uses. They are suitable for console and handrail panels, car panels, and panels, as well as floor panels. Call coding is carried out via the wiring. Separate carrier boards with coding via solder jumpers 1-8 are available for floor panels.
