A closed transition transfer switch (CTTS) is also called a make-before-break transfer switch. A typical emergency system uses open transition, so there is an inherent momentary interruption of power to the load when it is transferred from one available source to another (keeping in mind that the transfer may be occurring for reasons other than ...
The central switch may be an electromechanical switch or an electronic device using IGBT, EMT or other similar solid-state devices. The electronic central switch has only to open its circuit forcing the motor current to transfer into the 80% winding in a no-break, closed transition action.
This can also occur during the open-to-close (MAKE) transition due to contact bounce. The electric arc occurs between the contact points (electrodes) both during the transition from closed to open (BREAK) and from open to closed (make) when the contact gap is small and the voltage is high enough. Heating due to arcing and high current density ...

The National Association of Relay Manufacturers and its successor, the Relay and Switch Industry Association define 23 distinct forms of electrical contact found in relays and switches. [12] A normally closed (NC) contact pair is closed (in a conductive state) when it, or the device operating it, is in a deenergized state or relaxed state.
