144-20 /2I0 Description I50 - S583 19 General Notes The series contains indicators and illuminated pushbuttons with maintained and momentary action and one contact which may be normally closed or normally open (snap-action element for closing). The illuminated pushbuttons are fitted with snap- action or low-level switching systems. For technical data see pages 2 and 3. The front dimensions are 9 x 9 mm or 9 mm dia. Mounting Mounting from the front through the mounting hole is assured even when the wiring has already been attached (mounting dimensions and spacing see page 4.). The units are equipped with soldering or piug-in terminals. Lenses The flat lenses, made of polycarbonate, are obtainable in various colours. The transparent lens is available with trans- lucent or transparent support. Marking A limited amount of marking can be provided. IWumination Perfect illumination of the different coloured lenses is assured by filament lamps bipin T1 longlife (6-36 V) or LED bipin T1 (2,2 V) in the colours 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 apparent at all times from the position of the lens. All dimensions in mm. We reserve the right to modify technical data. How to order 19-XXX.0X5 |_____.

The switching system assures reliable switching of loads. Single-break momentary contact, as normally open or normally closed with 4 independent points of contact. Special features are the long life, extremely short rebound time and stable contact resistance. Contact material gold-plated Travel 2,8mm Actuating force (measured at the lens) 1,8N + 0,3 (180 g) Switch rating 10 pA/100 pV to 100 mA at 42 VAC/VOC Contact resistance Value as new s 50 mQ as per IEC 512-2, test 2b Rebound time typical < 100 ys Mechanical life 5 million operations Electric strength 2500 VAC, 50 Hz, 1 min between all terminals and earth, as per IEC 512-2-11. Terminals The universal terminals permit these units to be mounted on printed circuit boards (PCB). These terminals can also be used as soldering or plug-in terminals. For these terminals we can also supply a plug-in base which, when soldered on to the board, enables the switch to be plugged in.
