Southco Push To Close Latch Wing Knob

The Southco Push To Close Latch Wing Knob (Model 93-402) is a plastic push-button latch designed for equipment enclosures, instrument panels, and access doors requiring secure single-point fastening with integrated keyed locking. This compact latch combines push-to-open activation with optional ejector spring technology to eliminate rattles and unintended closure during transport or vibration, making it ideal for applications where secure panel retention and controlled access are priorities.

Specified to accommodate panel thicknesses from 0 to 12.7 mm (0.00 to 0.50 inches), this latch features a threaded body and nut installation system for reliable, vibration-resistant mounting. The wing knob grip range of 26.2 to 29.2 mm (1.03 to 1.15 inches) accommodates material variations, while key locking capability provides operator access control for sensitive equipment or compartments. The push-button mechanism requires deliberate user action to disengage, reducing accidental openings during normal handling or storage.

This latch is deployed across industrial equipment, portable instrumentation, portable electronics, tool cases, and military or defense platforms where compartment integrity during field transport is essential. The black plastic construction balances durability with weight savings. Field users appreciate the ejector spring option, which prevents lid sag and minimizes movement during vehicle transport or offshore environments where sustained vibration is inherent to operations. Single-hole installation simplifies retrofit applications where space constraints or panel redesign costs warrant selective component replacement rather than full enclosure redesign.
