DRD16SETR04 is a 16-position rotary DIP switch featuring a metal shaft actuator in a straight (vertical) configuration, designed for through-hole PCB mounting. The switch utilizes high-pressure pin-point sliding contacts with gold-flashed copper alloy contacts that provide 20,000 steps of operation and penetrate contaminants on the contact surface. It offers hexadecimal encoding with a common terminal internally connected, and features tin-lead plated terminals insert-molded into a polyester base. The device delivers a contact rating of 0.4 VA at 20 VDC with initial contact resistance of 50 milliohms maximum at 2 VDC, insulation resistance exceeding 1,000 megohms at 100 VDC, and dielectric strength of 300 VAC RMS. This switch is ideal for industrial control systems, test equipment, and configuration applications requiring reliable multi-position digital selection.
