LED ILLUMINATED PUSH BUTTONS.
 Binay LED Illuminated Switches offer high reliability due to their vibration-resistant nature, apart from the long life and low power consumption characteristic of LEDs. The long life, low current, low power consumption (0.5W at 230V AC), and vibration-resistant proper-ties of light emitting diodes (LEDs) make them an ideal choice for use in illuminated pushbutton switches and actuators. Moreover, the correct selection of the LED for ade-quate axial light intensity (a minimum of 50 millican-delas at 20mA in cluster form) ensures bright illumination for a positive indication. Uniform illumina-tion is achieved by proper refractive design of the top lens. For legend illumination, a diffuser is in-serted. BINAY LED Illuminated Pushbutton Switches come with a free-replacement guarantee against manu-facturing defects and operational failure for a period of one year from the date of purchase. The normal life of an LED, however, is 100,000 hours (11 years) calculated on a continuous burning basis, as com-pared to 1,000 hours for a properly manufactured filament lamp (a ratio of 100:1). As such, the ques-tion of replacement of an LED indicator does not normally arise. SERIES 16-L PUSHBUTTON SWITCHES BINAY 16-L Non-Illuminated Pushbutton switches are at present available in round bezels only, with 1NC + 1NO or 2NC + 2NO switching elements BINAY 16-L LED Illuminated Pushbutton switches can be provided with switching elements having a capacity of 2A and are available in 1NC + 1NO, 2NC +2 NO, 3NC + 3NO or 4NC + 4NO types. 
These push buttons have replaceable LED bulbs in midget groove caps which
are rated up to 28V AC or DC only. For operation at higher voltages, our
external HVCC (High Voltage Control Circuit) Unit of the appropriate
voltage should be used. (See description of HVCC Units below).The 16-L Series is available in solderable lug terminals only. SERIES 22.5f PUSHBUTTON ACTUATORS These are available in two types:
'T' TYPE PUSHBUTTON ACTUATOR (Available in both illuminated and non-illuminated versions): The illuminated versions have an integral actuator-cum-lamp body, and contain integral LED units in ratings up to 240V AC or DC. Switching elements (NC or NO) can be attached to one another (up to four elements on each side, for a total of 8 elements). Note: 'T' Type Pushbutton units can also be supplied in Bicolour (Red/Green, Red/Yellow, or Green/Yellow). In this case, the common input connection will be of the flying lead type.  'S' TYPE PUSHBUTTON ACTUATOR (Available in both illuminated and non-illuminated versions)): In the 'S' Type illu-minated version, the switching elements (1NC or 1NO, or 1NC + 1NO) are clipped on to appropriate slots on the unit housing on either side of the LED Module holder (which is itself clipped on to the centre slot of the housing). Bicolour versions are also available, with a flying lead for the common input. ADAPTERS FOR FITTING IN 30.5mm AND 25.5mm DIA. PANEL CUTOUTS Chrome-plated brass Adapters are available for fitting Series 22.5f Pushbutton Actuators in 25.5mm or 30.5mm diameter panel cutouts. Specify cutout size when ordering. HIGH VOLTAGE CONTROL CIRCUIT UNIT 16-L Illuminated Pushbutton Switches, which cannot be made integrally in higher voltages or in flasher versions, can also be used at these ratings (above 60V, e.g. 110V, 220V, or 440V) or with the flasher function with the inclusion of our High Voltage Control Circuit (HVCC) Units. These are of basic dimensions 90mmX25mmX25mm (LxBxW). The Unit is fitted externally to the switch, and is provided with terminals for input (from high-voltage source) and output (to switch illumination unit). The following types of HVCC Units are available:
