1. An actuating mechanism for a plunger-type switch having alternative open and closed conditions and having a plunger moveable
between an extended position and a retracted position whereby said switch condition is changed by the movement of the plunger;
said actuating mechanism comprising:
a) a housing having an upper surface; said housing being adapted to receive a plunger-type switch;
b) a spring having a first spring end, a second spring end and a middle portion; said spring being positioned within said
housing such that said first spring end is positioned in closely spaced relation to the plunger of a plunger-type switch received
within said housing with the plunger in the extended position; said middle portion of said spring bowing above said housing
upper surface through a spring receiving hole in said housing such that the application of a force to said middle portion
of said spring and directed toward said housing upper surface compresses said spring, advancing said first spring end toward
the switch received within said housing a distance sufficient to move the switch plunger to the retracted position and upon
removal of the force said first spring end advances away from the switch a distance sufficient to allow the switch plunger
to move to the extended position; and
c) a flexible sealing member secured to said housing upper surface and extending over said spring and enclosing said spring
receiving hole.
