  • solid PCB pins
  • contacts with abrasion resistant hard gold plating
  • extra sealed design
  • switches are solder and flux sealed and washable
  • excellent detent, once more improved
  • 100% electronic inspection and testing

Solid PCB pins ensure trouble-free assembly and safe connection. Contacts with abrasion resistant hard gold plating have low and stable contact resistance. ISO 9001 approved production together with 100% electronic final inspection and testing guarantee reliable operation. Figures are clearly visible and detention mechanism is precise for fast and easy operation. Many special designs are available on request or can be built according to customer's specification.
