Push Button and Switch Accessories and Spare Parts

Push button and switch accessories and spare parts are components such as contact blocks, LED modules, button heads, labels and protective covers that complete control push buttons, pilot lights, limit switches, pedals and crane controls, or that replace a faulty part. They are used to renew a worn contact or a burned-out lamp without replacing the whole device, to add an extra contact or light to an existing push button, and to protect the control element against accidental pressing and external influences. This page directly lists Siemens 3SU1 and 3SB push button and signaling accessories, for example 24 V AC/DC and 230 V AC LED modules and protective covers; spare parts for push buttons and signaling, limit switches, pedals, rotary limit switches and crane controls are in separate subgroups. Select the spare part first by the brand and series it belongs to, then by contact type (NO, NC), operating voltage and color for the LED module, connection style and IP rating. If the series the part fits is not stated in the product name, match the order code on your existing device with the product code.
