Abstract
A differential pressure operated electrical switch construction is provided and has a housing carrying a pair of rigid terminals and an electrical switch for electrically interconnecting the terminals together under the control of an actuator that is responsive to differential pressure acting across the same. The terminals have free ends angled toward each other and the switch comprises a movable contact member and a spring operatively associated therewith for urging the contact member into bridging contact with the free ends of the terminals to thereby place the terminals in electrical contact with each other.
