Abstract: A switch assembly including a base member and at least one pair of conductors provided on the base member which are to be electrically connected. An outer baffle extends over the base member and the conductors and is comprised of a conical wall having a key formed at the apex thereof and an outward flaring pad at the bottom thereof for engagement with the base member, the outer baffle including a recess beneath the key opening toward the base member. An inner baffle is dimensioned to be positioned within the outer baffle and includes a conical wall having a plug at the apex thereof and a pad formed at the bottom thereof. The plug is dimensioned to be received within the recess of the outer baffle such that the conical walls of the outer baffle and the inner baffle are symmetrical about a common axis. The pad on the inner baffle is spaced a predetermined distance above the base. A conductive element is provided on the inner baffle to electrically connect the conductors when the outer baffle collapses.
