ABSTRACT:
A normally open pressure responsive switch having upper and lower housings with a snap acting member and an electrically conductive member sandwiched therebetween. The housings each include a body with a hollow center portion and the lower housing has a contact in the center portion extending externally of the member. The snap acting member is in constant engagement with the sandwiched conductive member and normally out of engagement with the contact. When pressure is applied which is sufficient to cause the snap acting member to snap connection is made with the electrically conductive member in the lower assembly. An elastomeric sealing member is mounted in the upper housing and has a neck portion received in the hollow center portion, an integrally attached flange biased against the electrically conductive member and lower housing and an integrally attached lobe extending above the upper housing to seal off the hollow center portion when the switch is mounted at a switch receiving seat.
