31/32 425-093 to 925-299Description 31 Genera! Notes The series 31 illuminated pushbuttons are equipped with snap- action or low-level switching elements. For technical data see pages 2-4. In addition to the standard contacts (gold-plated silver), silver contacts can also be ordered. The front dimensions of these units are 18 x 24 mm or 18 mm dia. tn addition to a number of illuminated pushbuttons, the customer can choose from a wide range of other units and accessories having the same front and mounting dimensions: indicators, keylock switches, flashers, segment displays, buzzers, illuminated pushbuttons with microfuse, etc. (For keylock switches see series 51 or 61.) Mounting Mounting from the front through the mounting hole is assured even when the wiring has already been attached (mounting dimensions and spacing see pages 5-7). The universal terminals of the low-level switching elements permit mounting on printed circuit boards (PCB). These terminals are also suitable for dip soldering. For these terminals we can also supply a plug-in base which, when sol- dered on to the board, enables the switch to be plugged in. All rectangular switches, as well as the square and round key- lock switches are secured against rotation. Lenses The flat or concave lenses, made of polymethyl methacrylate, are obtainable in various colours, as well as translucent or trans- parent. Marking For engravings, hot stamping and film inserts, see under Marking on page 29. Htumination Perfect illumination of the different coloured lenses is assured by midget-grooved lamps T 1% (6-60 V). If the supply voltage is above 60 V, an external dropping resistor or capacitor must be used. Multi-LED midget-grooved lamps T 1% (6, 12, 24, 48 V) are available in the colours red, yellow and green. Due to the high surface temperature, resistors may not be soldered direct to the terminals of the pushbuttons. See under Lamp accessories on page 22. Position indication When a switch with maintained action is actuated, the lens remains in the depressed position mechanically. The state of the switch is apparent at ail times from the position of the lens. All dimensions in mm. We reserve the right to modify technical data.

Engraving Typefaces In addition to the most commonly used world languages (see DIN 1451) with close spacing, the following typefaces are available: Scandinavian, Slavian, Greek, Russian. Coloured filling of engraving Red, blue and black lenses have the engraving filled with white. Lenses of other colours have the engraving filled with black. Symbols A list of the symbols available can be supplied on request. 2. Hot stamping For large batches it is worth while to have the lettering produced by hot stamping. Typefaces For letters and figures, typefaces with 2,5 mm, 3mm and 4 mm are available. Symbols A list of the symbols available can be supplied on request. Important! Before engraving, check the position of the illuminated pushbutton or indicator. oc rf ABC 7 AB | abe aby Horizontal mounting Vertical mounting 9) & 2 g p 2 o 2 o 2 s |S g }2 |s g j}2 {8s g |e |8s g |}2 |8 = 5 = 2 2 2 a = 2 2 = 2 2 = 2 3 6 S 6 3 3 6 | 3 3 5 | 3 3 z | 2 |22/32 | 8 |82)32) |82)82 |) 8 | 82] Be Se|/2e| 5 |Ss/5s ) |53|/53/ 5 158/53) | 53/85 re Fe 2 2af/2a 2 za |;228 z za l/2a 2 za f)/22 h Ss (caps) (small) (caps) (smal!)

Film inserts Instead of using engraving, the lenses can be fitted with transparent film inserts. For this purpose, though, it is advisable to use transparent lenses. When a smoked lens is used, the lettering does not become visible until the lamp lights. To insert the film, the feet of the lens support have to be pushed together far enough to enable the lens to be lifted off easily.
