C&K Switches TDB Ultra-miniature SMT Half-pitch DIP Switches

C&K Switches TDB Ultra-miniature SMT Half-pitch DIP Switches offer gold-plated contacts, a 100mΩ contact resistance, and 4.9N operating force. The ultra-miniature design is achieved by the reduction of the internal mechanism, enabling high-density mounting. TDB switches are sealed with top tape to support washable processing. Suitable applications for TDB switches from C&K Switches include industrial control equipment, IoT devices, power supplies, and inverter systems.
