SK-43D03 Side Handle Toggle Switch_4P3T Four-Pole Three-Position_D Series Standard Travel Side-Insert DIP_Multi-Channel Three-Mode Synchronous Switching_Sinyin Electronic Original
Compact layout for industrial control panels | Multi-mode selection for embedded devices | Three-state output integration for PLC | High-reliability domestic alternative solution
SK-43D03 is a 4P3T (four-pole three-position) side handle toggle switch from Sinyin Electronic' D Series (standard travel), specifically optimized for multi-channel three-mode synchronous control in limited spaces. A single component integrates 4 independent circuits with 3 working states (e.g., OFF → A → B), replacing 12 single-pole switches, significantly reducing BOM costs, PCB area, and system complexity. The product features a nickel-plated metal shielding shell and side-insert DIP packaging, with a rated load of DC 50V 0.3A (directly specified on the drawing), and complies with RoHS 2.0 and REACH environmental directives. ⚠️ Note: It shares the same dimensions as SK-42H13 but differs in travel (2mm vs 4mm); mixing them is strictly prohibited. Before selection, confirm that the human-machine interaction requirement is "standard operation" rather than "strong tactile feedback."
