Patent number: 6943655Abstract: A direct current contactor having at least one low current terminal and at least two high current terminals is disclosed. The low current terminal is connected to a spring, which is nested in a chimney-shaped receptacle, where it is coupled to the contactor's coil. The chimney shaped receptacle also has a slot that receives a terminal blade that electrically connects the spring to the coil. The housing of the solenoid is designed with longitudinally extending channels that receive the receptacles, which prevents the assembly from rotating within the housing unit. Each terminal is provided with ribbed and knurled areas to restrict rotation of the terminal in the housing and the mating connection while tightening.Type: GrantFiled: February 27, 2004Date of Patent: September 13, 2005Assignee: Trombetta, LLCInventors: Todd McMahon, Dennis A. Maller

Patent number: 6538345Abstract: An electrical control module, including a control circuit, and voltage rectifier for controlling a solenoid. The control circuit is adapted for use in a transfer switch receiving power from two power sources and sending power to a single load, such as a commercial building or hospital. The control circuit and solenoid are designed to work over a broad range of voltages to quickly and efficiently transfer power from the first power source to the second. The circuit is particularly well suited for use in a closed transition transfer switch where the second source is connected before the first source is disconnected.Type: GrantFiled: October 24, 2000Date of Patent: March 25, 2003Assignee: Trombetta, LLCInventor: Dennis A.

Patent number: 5663700Abstract: A sound dampened solenoid utilizes pneumatic dampening to quiet the sound during the plunger's movement. An O-ring is mounted around the outer diameter of the pole piece thus sealing the pole piece to the solenoid tube. A seal is placed in the pole piece opening where the plunger push rod passes through. A pair of low friction wear bands are wrapped around the plunger. Small gaps are formed where the ends of each wear band meet. A second O-ring is located under one of the wear bands to form a seal between the plunger and the tube. In a pull solenoid, when the solenoid is energized the plunger begins to accelerate toward the pole piece causing the volume of air within the tube between the plunger assembly and pole piece to shrink. The only path for air trapped within to escape is through the gaps in the wear bands. Air is forced through the gaps at a slower rate than the rate of volume change. Air pressure within the volume rises slowing the plunger acceleration and quieting its operation.Type: GrantFiled: August 25, 1995Date of Patent: September 2, 1997Assignee: Trombetta CorporationInventors: Glen C. Spence, Dennis A. Maller
