N & H Technology GmbH offers vandal-proof pushbuttons with individual, backlit symbols. This is made possible by a new material mix in which the pressure hood of the aluminum pushbutton is replaced by a plastic cap. The symbols are engraved by a laser. Customer-specific symbols, such as a company logo, are also possible on request. The icons can be backlit in almost any color with single LED or dual color. Customized, the complete pushbutton can also be anodized in an individual color. The engraving of the key surface is possible with push-buttons with a mounting diameter from 16mm. The pushbutton shown here belongs to the S1AGQ series and has a mounting diameter of 19mm. The protection class is IP67 / IK09. The switching function can be either latching or momentary. Optionally, it can be used as NC or NO, even with double occupancy. The operating force is 3-5N. Pre-assembly with cable or plug is possible. With a lifetime of over 1 million cycles, the pushbutton is durable and reliable.
