51 01 02 03 04 10 14 Marking General notes 3. Film inserts Instead of using engraving the lenses can be fitted with transparent film inserts, as an alternative. For this purpose, though, it is advisible to use transparent lenses. In the case of use of a smoke-black lens the fitted film becomes readable only if the lamp is on. The film thickness is 0.2 mm. Important : Consider pushbutton mounting orientation befor specifying engraving characters! 1.

51 01 02 03 04 10 14 17 Application guidelines Suppressor circuits When switching inductive loads such as relays, DC motors, and DC solenoids, it is always important to absorb surges (e. g. with a diode) to protect the contacts. When these inductive loads are switched off, a counter emf can severely damage switch contacts and greatly shorten lifetime. Fig. 1 shows an inductive load with a free-wheeling diode connected in parallel.
