Placing the switch such that the direction of switch
operation is vertical and then gradually increasing the
5.1 Actuating Force load applied to the center of the stem, the maximum
load required for the stem to come to a stop shall be
measured.
Placing the switch such that the direction of switch
operation is vertical and then applying a static load
twice the actuating force to the center of the stem,the
travel distance for the stem to come to a stop shall be
measured.
The sample switch is installed such that the direction
of switch operation is vertical and,upon depression of
the stem in its center the whole travel distance ,the
force of the stem to return to its free position shall be
measured.
Placing the switch such that the direction of switch
operation is vertical, the maximum force to withstand a
