What is the difference between a spring latch and a Deadlatch?
Once you turn the handle, the bolt retracts from the strike plate. Think of a spring latch as a pinball machine: when you play, you pull the plunger, and the pressure from the springs sends the ball flying. Instead, the springs release the latch with a turn of the handle. Conversely, deadlatches are not spring-loaded.
How do spring-loaded locks work?
A spring latch is locked with a spring compression so that it will not be released because of vibration. The arm is made of different materials to cater to the tightening strength and for it to be rustproof. The spring-loaded latch mechanism makes it easy and efficient to do any particular job.
How does a spring loaded mechanism work?
In the cases of compression and extension springs, the coils are compressed or extended linearly which creates a force that opposes that motion. Once the load is released from the spring it will oscillate linearly back and forth about its “relaxed” position.

How does a constant force spring work?
It is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring, but at a nearly constant (zero) rate.

How does a retractable spring mechanism work?
Retractable Cord Reels
They use a spring mechanism to provide the retraction force. As the cord is uncoiled and pulled out for use, tension builds up on the steel torsion spring. Once the electrical power is no longer needed, the stored energy in the torsion spring is released, retracting the cord back to the reel.
How do indexing plungers work?
Indexing plungers are used in machine and fixture applications to lock items in place, especially when indexing a range of motion or a series of positions. A typical indexing plunger features a knob or ring attached to a spring loaded pin. When the knob is pulled, the pin is retracted, allowing for free movement.
