SPDT 2-Position 1121 Industrial Heavy-Duty Toggle Switch – 3-Terminal,
The 1121 Toggle Switch is a high-capacity, industrial-grade panel control switch engineered for seamless, reliable alternating circuit control. Featuring a rugged, high-leverage metal bat lever handle, this switch provides crisp mechanical feedback and smooth manual actuation. It operates via a 2-position maintained mechanism (ON-ON), allowing operators to instantly toggle power or signals between two separate circuits without a center-off interruption. Outfitted with 3 robust screw terminals forming a Single Pole Double Throw (SPDT) configuration, it delivers excellent electrical conductivity, high thermal endurance, and a prolonged service life across factory machinery, power distribution networks, and heavy-duty equipment setups.
