Abstract
A bracket 14 for mounting a lead frame 12 having pressure responsive electrical switches 20 is provided with a pair of bores 88 through the bracket at each switch station in alignment with recessed portions 78 and 86 in the bottom surface of the switch housing. A layer 92 of filter material is disposed between the bores and the recessed portions so that fluid flowing through the bores into the recessed portions will be forced to flow through the filter material to exclude particles of contamination larger than a selected size.
