Abstract
Improved actuating mechanisms are provided in pressure switches controlling water tub fill levels in domestic appliances such as dishwashers, washing machines, etc. The mechanisms include a snap blade construction which improves contact point wear characteristics; an orifice molded into the switch's plastic body which averages transient surges in water tub levels during operation; a simplified plunger arrangement utilizing an especially configured actuator for establishing trip and reset levels of the switch; and a snap blade configuration which minimizes 'contact bounce' after the contact moves from one stationary contact to the other.
