Torsion Springs

Torsion Springs

Found in everyday tools such as clips, clothespins, mousetraps, and swing-down tailgates, torsion springs consist of a coil spring with a leg on each end. The legs are set at an angle to each other and are squeezed together to compress the spring. When released, the legs push away from each other, causing any parts that are attached to the legs to move with them.

The spring's rotation angle represents the angle between the legs of the spring and the maximum angle of rotation for the spring.

90° Rotation Angle

Use these 90° rotation torsion springs in items that need to move from horizontal to vertical, such as tailgates and flip-out camera lenses.
