I checked the downward force just after the light turns on, and it increases then. It is not when the horizontal pressure is applied but when the light turns on that that downward force increases. I can still push the top ferrule up a little but it is more difficult when the light is on. | I checked the downward force just after the light turns on, and it increases then.
