You should measure the differences between the LS-32 and LS-40 again.
They use the same spring and almost the same switches and same exterior measurement actuator but that is where the similarities end.
The different pivots give a different feel but the biggest difference is that because the switch assembly sits lower it causes the the LS-40 to hit the switches and gate earlier (shorter throw). The lower you position the switches the sooner they engage. And if you measure both PCBs the switches are closer together on the LS-40 adding on the short throw.
The LS-40 has a taller shaft that gives the illusion that they have similar throw distances because a taller shaft travels a longer distance than a shorter shaft. Those who bought the LS-32 40th anniversary stick can install the +4mm taller than stock shaft to match the LS-40 shaft height from the pivot and it’s really easy to see the LS-40 stops much sooner.
The bottom part of the LS-40 shaft is also longer because the switches sit lower on the body.
If you have an original model LS-32 you will also notice that the switches are closer together on the LS-40 because the deadzone is much smaller on the LS-40. (The deadzone is small on the new 2017 LS-32 because of the bent switch metal tabs).
And the spring feels a tiny bit lighter on the LS-40 because the bottom part of the shaft is longer so the spring is less compressed and the shaft is taller giving it more leverage.
The LS-40 also eliminates the pivot from rising when pushed against the gate because the angle is smaller and the pivot is different.
The construction on the LS-32 is “higher quality” because the bottom part is metal and the shaft is heavier. If you install them on a super solid metal panel you will notice that the LS-32 feels more solid because you can feel very small but noticeable differences between the shaft hitting the all plastic body vs the part metal body of the LS-32.
They are very different sticks after you use both for some time. Both are absolutely awesome.
