Abstract
A pressure responsive electrical switch (,) has a base (,) formed with a bottom wall (,) having a top surface (,) formed with a generally disc seat (,). A recess (,) is formed in the bottom wall through the top surface within the area defined by the disc seat and with first and second bores (,) formed through the bottom wall aligned with the recess. Integrally formed combination terminal and movable contact arm members (,) each have a first portion (,) serving as a respective terminal and a second, movable contact arm portion (,) swaged to an attenuated thickness. The movable contact arm portions extend side by side transversely across the bottom surface of the recess in generally opposite directions and with a free distal contact end portion (,) extending slightly above a disc seat formed on the top surface. An electrically conductive, snap-acting disc (,) is disposed on the disc seat out of engagement with the contact end portions (,) when the disc placed in pressure receiving communication with a fluid pressure source to be monitored is in one dished configuration at pressures below a selected actuation level and in electrical engagement with the contact end portions when the pressure of the fluid exceeds the actuation level. An alternate embodiment includes a calibration beam (,) on at least one of first and second combination terminal, movable contact arm members (,) to allow adjustment of the release pressure level of the snap acting disc.
