Series in this family
- 3SU1 Pushbuttons & Selectors — 23 catalogued parts under the 3SU1 order-number range, the device-level series covering the individual pushbutton and selector catalogue numbers.
3SU devices are assembled from a front element, a holder and contact or LED modules, and each element carries its own 3SU1 order number. Use this family page to understand how the line is organised, then open the 3SU1 series for the catalogued device numbers themselves. If the element you need is not listed, send the complete 3SU1 order number with a quote request.
