  • Early break inverter bypass safety switch
    Patent number: 9136696
    Abstract: An early break bypass switch provides a modular system for bypassing an inverter when needed without allowing switching induced damage to the inverter. In an embodiment of the invention, a shaft-mounted switch provides rotatable cams and sliding followers for positive opening contacts while providing an auxiliary switch section for breaking and making contact to an inverter controller in a specific sequence relative to inverter power. In this way, the inverter is both isolated from the line power and also protected during switching from being damaged by switching-induced spikes and transient signals and surges.

  • Disconnect switch with early break feature
    Patent number: 7324314
    Abstract: A disconnect switch that provides a simple and economical means for preventing the possibility of stray/surge current from damaging the solid state components of an inverter drive is provided. The disconnect switch includes early break auxiliary contact(s) that open before the standard power contacts when the switch is turned off by an operator and close after the standard power contacts when the switch is turned on by an operator.

  • Cam operated inverter bypass safety switch
    Patent number: 5721449
    Abstract: An inverter by pass safety switch for rerouting electrical power either through or around AC variable frequency inverter drives during electrical disturbances, thus allowing a motor to continue operation. The switch works in a mechanical fashion, and comprises a contact block containing electrical contacts and cams operably connected to the contacts and mounted on a shaft that can be turned by an operator. The cams are shaped and mounted on the shaft in such a way to provide a desired switching pattern when the shaft is manually rotated.
