New Lever-Actuated Plunger Enables Fast Removal of Electronic Components

Southco has extended its successful line of captive hardware with a new version that features lever-actuated operation for faster and easier latching and unlatching of electronic components. Southco’s compact lever-actuated 56 Spring-Loaded Plunger offers an improved grip for simplified hand operation and saves time when installing or removing components in tight spaces.

Southco’s lever-actuated 56 Spring-Loaded Plunger boasts a useful hold-open feature when the lever is actuated, providing clear visual confirmation when the plunger is unlatched and keeping the plunger in a retracted position for easy removal. Actuated with a single motion, the lever-actuated 56 Spring-Loaded Plunger saves time in comparison to current round knob, hold-open versions requiring a two-step lift and turn operation to unfasten.

The easy to grip lever-actuated 56 Spring-Loaded Plunger provides quick hand operation for latching and unlatching, facilitating the installation and replacement of components used in various electronics applications including HDD carriers, metal trays and power supplies. Additionally, the lever-actuated 56 Spring-Loaded Plunger is available in prism colors for differentiation between application zones and is available in thread-in, flare-in and press-in installation options.
