The MS-156C Series is a subminiature coaxial switch designed for high-frequency circuit inspection in portable terminals. It features a space-saving, low-profile design (1.35 mm protrusion) and is lightweight (0.014 g). The switch allows for simple circuit verification by inserting an external plug into the board-mounted receptacle, which redirects the circuit from its normal condition to the plug side.
Applications: Portable terminals, ETC, notebook computers (Bluetooth), wireless LAN, POS terminals, GPS terminals, PDA, and small devices requiring antenna/circuit performance verification.
