D2EW Sealed Ultra-Miniature Basic Switch

D2EW, which can be operated from multiple angles, is an ultra-subminiature switch that can be easily integrated into small available spaces. This switch eliminates the need for a lever, improving its cost performance and increasing its flexibility in customer unit design. Downsizing the switch operating mechanism ensures a reduction in materials used, component count, design man-hours, and production man-hours.

Features

  • The industry’s smallest class *(8.3 x 7.0 x 5.3 mm) D2GW equivalent size
  • A left-right asymmetrical post shape prevents misassembly
  • A sliding contact structure delivers quiet operation
  • Contributes to energy saving (minimum applicable load 50 µA
