M28W640ECB85ZB6F Datasheet

General descrrption EMF is a complete illuminated pushbutton switches programme for screw on panel mounting (mounting hole diameter 16 mm) The forms of lenses are available in the dimensions rectangular 18 x 24 mm, square 18 x 18 mm and round diameter 18 mm. The pushbutton switches are equipped with snap action element and 1-4 contact blocks Each contact block can be used as N C or N O or change-over contact (for change-over contact ext connection between terminals 2 and 4) Contacts in one section must be same polarity. EMF illuminated pushbutton switches can be fitted with contactless elements on request Separation of the individual switching elements by contactless units permits high and low voltages to be applied to the same pushbutton switch The 4 tin-plated terminals of each block are absolutely flux- proof The lense of EMF are available in 11 different colours and can be illuminated by Midget-Groove T l3/4 incandescent lamps or LED The switching positcons of the alternate version of the pushbutton switches is always indicated by the position of lens By use of neon lamps with external resistor1250 V~, please conslder relevant standards and approvals.
