Review on π Leviton 1221-2WL 20-Amp, 120/277-Volt, Toggle Locking Single-Pole AC Quiet Switch, Extra Heavy Duty Spec Grade - White by Jim Agosta
Works well. good for welders and accessories
I fitted them for external switches that were replaced with toroidal chamber/tips because the wrong switch was selected. permanently used to disable external ring chambers.
Pros
- Brass combi-head screws on heavy equipment, steel combi-head screws on other equipment
Cons
- unreliable
