DIP switches (Dual Inline Package switches) provide a set of small binary (ON/OFF) selector switches in a single package — used for hardware configuration, address setting, and mode selection in PLC input modules, industrial automation equipment, telecom line cards, security systems, HVAC zone controllers, and older computer motherboards. Our DIP switch inventory covers piano (slide) type and rotary-coded types from Bourns (SWA/SWD series), Nidec (COPAL SW series), Grayhill (94H series), Omron (A6D/A6R series), and TI/C&K (DR- series) — with 1 to 16 positions, in both SMD (gull-wing and J-lead) and through-hole packages, with gold or tin contact plating.
Rotary-coded and sealed DIP switches for industrial and outdoor environments often have long lead times. Welllinkchips stocks both standard piano-type and rotary-coded DIP switch configurations, including discontinued part numbers and hard-to-find pole-count variants for legacy PLC and telecom equipment repair.
