218 Half Pitch, SMD DIP Switches CTS Electronic Components 218 Half Pitch, SMD DIP Switches offer a 100mΩ contact resistance, 50VDC non-switching rating, and 100MΩ insulation resistance. The 218 switches feature an optional sealed structure that is optimized for board washing during the soldering process. These switches have low-profile actuators that prevent accidental actuation and gull-wing and 'J' bend terminal configurations. CTS 218 Half Pitch, SMD DIP Switches are ideal for servers, security, and HVAC systems.
