The FA410/2B DPDT Power Tool Lock On Trigger Switch is a twopole, doublethrow (DPDT) trigger switch designed for power tools. It features a lockon function that allows continuous operation without keeping the trigger pressed, helping to reduce hand fatigue during extended use. This model is intended as a replacement part for tools that require a DPDT lockon trigger and is compatible with the FA410/2B configuration. Key benefits Hands operation: lockon mechanism enables extended runs without continual trigger pressure. Reliable control: DPDT (twopole, doublethrow) configuration supports robust switching for power tool circuits. Easy replacement: designed to fit tools that use the FA410/2B DPDT trigger switch, providing a straightforward upgrade or path. Enhanced tool life: a purposebuilt switch intended to worn or failing triggers, restoring consistent performance. Flexible wiring options: DPDT design allows various wiring configurations to match tool circuitry and potential forward/reverse control needs. Key attributes Functionality: lockon trigger capability with DPDT switching for versatile circuit control. Compatibility: specifically aligned with FA410/2B DPDT power tool applications as a replacement switch. Size and form factor: compact enough to fit standard power tool trigger cavities that support this model. Construction: robust internal mechanism with a durable external housing designed for repeated actuation. Performance: designed for smooth actuation and reliable operation in typical power tool duty cycles. Materials: built with durable internal contacts and a sturdy housing to endure regular use. Control features: lockon ability combined with DPDT configuration to support multicircuit or reverse wiring in compatible tools. Applications and use cases Replacing a worn or failing trigger in a corded drill to restore lockon operation for extended drilling sessions. Implementing continuous operation in sanding or grinding tasks, reducing operator fatigue during long runs. Replacing the trigger in tools that use DPDT switching to support forward/reverse or alternative circuit configurations in compatible equipment. Notes This description reflects the FA410/2B DPDT Power Tool Lock On Trigger Switch and its expected role as a replacement component for tools that require a DPDT lockon trigger. Compatibility should be verified with the specific tool model and wiring configuration prior to installation.
