ADP04S04 is a 4-position DIP switch assembly manufactured by TE Connectivity (ALCOSWITCH brand) designed for through-hole PCB mounting applications. The switch features a PPS 94V-O black case and cover with a white nylon PA6T 94V-O actuator, and employs gold-plated copper alloy contacts for both moving and fixed terminals to ensure reliable electrical performance. Electrically, it is rated for a maximum switching current of 100 milliamps at 24V DC, with a minimum switching capability of 0.10 microamps at 1 millivolt, and a maximum non-switching current of 1 ampere at 5V DC. The switch exhibits a contact resistance of 50 milliohms maximum, an insulation resistance of 100 megohms minimum at 100 VDC, and a dielectric strength of 500 VAC, with a minimum life expectancy of 1000 cycles. It is commonly used in industrial control systems, consumer electronics, and instrumentation where reliable switching and configuration selection are required.
