Technical Information
Series 19N
The miniature microswitch (the standard V4 size) has been designed in line with similar
competitive products, but because of automation, offers consistent high quality levels for
volume applications, at no extra cost. The switch mechanism used is the well proven spring
and blade method, and is offered in a choice of operating forces.
Other standard options include gold or silver contacts; PCB, solder or QC terminals, and
integral wire lead versions. All versions have a fully sealed base right up to the bottom
opening. In addition, sealed button versions are totally environmentally sealed.
