Push-to-Close Latching; The Secret of Simple Operation

PushWhen it comes to convenience, it’s easy to take even the simplest of operations for granted. This week we take a closer look at a simple operation that often goes unnoticed: push-to-close latching.

Push-to-close latching technology is in everything from car doors and glove boxes to storage cabinets and office furniture. Its simple functionality allows us to securely close a panel and not have to worry about having to manually re-latch it.

In a push-to-close application, the cam rotates freely from the “closed”

position as it contacts the frame or keeper, and an integral spring pushes the cam back into the engaged position once the cam clears the keeper. Southco’s E5 Push-to-Close Cam Latch features push-to-close convenience by incorporating a spring-loaded ramped cam or actuator for single or multi-point operation.

Basically it works like this: Think about how often you open and close a cabinet door. Adding our E5 to this application means that when you push the door towards its frame, a ramp-shaped cam rotates as it contacts the frame, the cam then springs back and moves behind the frame to achieve latching.

The unsung value that push-to-close operation brings to your application design is paramount. Incorporating an action as simple as not having to manually re-lock a door every time it is closed can bring great value to end users in a wide array of industries.
