Abstract
A differential pressure operated electrical switch construction and method of making the same are provided, the construction having a housing carrying a pair of substantially straight parallel 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. One of the terminals has an end provided with a substantially rectangular opening passing transversely and completely therethrough and defining a substantially straight interior edge of the one terminal and the switch includes a movable switch blade having one end carried by the other of the terminals and having another end disposed in the opening for engaging against the edge to thereby place the terminals in electrical contact with each other.
