D501J12S205DQA is a miniature snap-in power rocker switch from the D Series, designed for general-purpose switching applications in small appliances, computers, and medical instrumentation. The switch features a single-pole configuration with quick-connect (05) twisted terminals, rated for 10 amps at 125 VAC (50/60 Hz) and 10 amps at 30 VDC resistive load, with an electrical life of 10,000 make-and-break cycles at full load. The actuator and housing are constructed from 6/6 nylon (UL 94V-2) in black matte finish, with movable contacts made from coin silver and silver-plated stationary contacts and terminals. The switch offers excellent insulation resistance of 10? O minimum and dielectric strength of 1,000 Vrms minimum at sea level, making it suitable for reliable operation in demanding environments. Its compact design with snap-in mounting and recessed bracket options helps prevent accidental actuation, while RoHS compliance ensures environmental compatibility.
