01 Description General Notes Number structure The Series 01 illuminated pushbuttons are equipped with snap- 01-XXX.0XX action, low level switching elements. Kind of terminals In addition to the standard contacts (gold-plated silver), on request Contact material silver contacts for switching elements 2.8 mm plug-in terminals are available. The front dimensions of these units are 18 x 24 mm, Switch variant 01 18 x 18 mm or 18 mm dia. 01-9XX.X Lens In addition to a number of illuminated pushbuttons, the customer can choose from a wide range of other units and accessories having the Example: -Illuminated pushbutton, circular same front and mounting dimensions. momentary action, gold-plated silver contact soldered terminals,1 switching element Mounting 01-131.025 Mount from the front through the mounting hole. -Lens red The universal terminals of the low-level switching elements permit 01-983.2 them to be mounted on printed circuit boards (PCB). These terminals are also suitable for dip soldering. For these termi- nals we can also supply a plug-in base which, when soldered on to Specimen order the board, enables the switch to be plugged in. All rectangular swit- ches are secured against rotation. Indicator: - indicator, soldering terminals, 18 x 24 mm 01-040.005 Lenses Recommended accessories: - lens, blue, 18 x 24 mm 01-982.6 The flat lenses, made of polymethyl methacrylate, are obtainable in - LED, 1 chip, 12 VDC, white 10-2109.3139 various colours, as well as translucent or transparent. Marking For engraving, hot stamping and film inserts, see under Marking on page 33. Illumination Perfect illumination of the different coloured lenses is assured by lamps T 5,5 (6-60 V). For supply voltages above 60 V, it is necessary to use a voltage re- duction element (external series resistor, capacitor, or transformer). Do not solder the terminals directly, because of the high surface tem- perature. Multi-LED lamps T 5,5 (6, 12, 24, 48 V) are available in the colours white, red, yellow and green. Position Indication When a switch with maintained action is actuated, the lens remains in the depressed position mechanically. The state of the switch is ap- parent at all times from the position of the lens. All dimensions in mm.
