D4C0406N is a ceramic-insulated rotary switch from the D4 Series, featuring 4 poles with 2 poles per section across 2 sections, supporting 2 to 6 active positions with non-shorting contacts. The switch utilizes a single-ball, hill and valley index mechanism with a positive 30° indexing angle and adjustable stops, delivering a minimum stop strength of 10 in. lbs. Electrically, it is rated for 1.5 amps at 28 VDC (make and break resistive load) with a current carrying capacity of 9 amps, dielectric strength of 1,500 VAC, and average initial contact resistance of 3.5 milliohms. The ceramic insulation provides superior insulation resistance exceeding 1,000,000 megoohms, and the switch features a 1.437" diameter with solder lug terminals and a 3/8-32 thread mounting surface. This economical and versatile switch is ideal for applications requiring reliable multi-position selection in control systems, instrumentation, and industrial equipment.
