SHIRO88: Moved to WRNO-FM in new Orleans

SHIRO88 As with forms X and Y, both current paths involve two contacts in series, mechanically linked and operated by a single actuator. Form X or double-make contacts are equivalent to two Form A contacts in series, mechanically linked and operated by a single actuator, and can also be described as SPST-NO contacts. Form Y or double-break contacts are equivalent to two Form B contacts in series, mechanically linked and operated by a single actuator, and can also be described as SPST-NC contacts. This is not always the case, Form C contacts follow this rule, while the otherwise equivalent Form D contacts follow the opposite rule, make before break. Form K contacts (center-off) differ from Form C in that there is a center-off or normally-open position where neither connection is made. These contacts are quite frequently found in electrical switches and relays as the common contact element provides a mechanically economical method of providing a higher contact count. In most cases, the rule is break-before-make or B-B-M; that is, the NO and NC contacts are never simultaneously closed during the transition between states.|Mounted Inside a Pull Switch
