The 12TW1-3F is a 2-pole, double-throw (DPDT) miniature toggle switch from the TW Series, designed for high-reliability applications. It features a sealed, pull-to-unlock lever on a 15/32-inch bushing, which prevents accidental actuation. This 2-position switch provides maintained ON-ON functionality, making a '2-1 & 5-4 ON' circuit in the keyway position and a '2-3 & 5-6 ON' circuit in the opposite position. Qualified to MIL-S-83781 and UL recognized, it operates over a temperature range of -65°C to +71°C. Its robust construction makes it ideal for industrial controls, military hardware, and aerospace applications where safety and durability are critical.
