Seimitsu +20% dynamic hard spring actuator kit (for compact joysticks)

A combined hard spring and special actuator kit for compact joysticks, manufactured by Seimitsu. 

Background:

The special model joystick LSH-56-01 comes standard with a specialised irregular spring which has dual characteristics (return emphasis or input emphasis**) that can be chosen by the user. To achieve this variability, the spring is tightly coiled at one end and widely spaced at the other, hence irregular. Facilitation of this spring required a dedicated actuator to be fitted.

This newly released kit contains a +20% harder variant of the irregular spring in addition to the special actuator required.

Therefore, use of this kit allows the unique and upgraded performance of the LSH-56-01 to be achieved with the following compatible joystick models: LS-56/58/60/62/SELS 70X. Previously, the irregular spring was only available in the specialised and limited edition LSH-56-01.

The additional use case is for owners of the LSH-56-01 who wish to experiment with the harder spring to tune the ideal joystick setup for a desired control preference. 

(** Return emphasis relates to increasing the speed at which the shaft returns to centre. Input emphasis will engage directions faster and therefore increase the speed of inputs)
