DPST 2-Position 1221 Industrial Heavy-Duty Toggle Switch – 4-Terminal,
The 1221 Toggle Switch is a high-capacity, heavy-duty industrial panel switch designed for reliable, straightforward power control. Featuring a classic, high-leverage metal bat lever handle, this switch provides crisp manual execution and smooth actuation. It operates via a 2-position maintained mechanism (ON-OFF), allowing operators to safely connect or completely isolate primary power lines. Configured with 4 robust screw terminals in a Double Pole Single Throw (DPST) layout, it enables the simultaneous management of two separate electrical lines, providing excellent electrical conductivity, thermal endurance, and extended performance in industrial control panels, machinery, and automotive systems.
