JJCHLUJ100NCPMRTR is a compact detector switch from the JJC series designed for signal switching in electronic devices across automotive, instrumentation, telecommunications, and consumer applications. The switch features a horizontal side stem left orientation with J-bend mounting, 1.0 mm height, and normally closed (NC) circuit configuration with a metal cover and silver plating. It operates momentarily with a current range of 50 µA at 3 VDC minimum to 1 mA at 5 VDC maximum, and maintains contact resistance of 2 O maximum when actuated at 2.3 mm. The device is rated for 50,000 cycles minimum operating life, operates reliably across -10°C to 60°C, and meets RoHS compliance with halogen and lead-free construction. Its compact 3.5 × 3.3 mm body size and robust mechanical design make it ideal for space-constrained applications in digital cameras, notebooks, and automotive systems requiring reliable signal detection.
