SPDT may refer to: Single pole, double throw, a simple type of changeover electrical switch; Single Point Diamond Turning, a type of mechanical machining using diamond-tipped cutting elements; SCSI Pass-Through Direct, (SPTD) is a proprietary device driver and application programming interface (API)
The SPDR S&P 500 ETF Trust is an exchange-traded fund which trades on the NYSE Arca under the symbol SPY (NYSE Arca: SPY).The ETF is designed to track the S&P 500 index by holding a portfolio comprising all 500 companies on the index. [1]
An alternate notation for Form C is SPDT. [ 12 ] 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.
Similar to SPDT. Some suppliers use SPCO/SPTT for switches with a stable off position in the centre and SPDT for those without. Serial switch or two-circuit switch [citation needed] DPST (2P1T) Double pole, single throw: Double pole: Double pole: Equivalent to two SPST switches controlled by a single mechanism. DPDT (2P2T) Double pole, double throw
A different standard, European Norm (EN) 50005 recommends terminal numbering for general application relays (e.g. 11/12/14/A1/A2 for a SPDT relay) that may nevertheless be applied to automobiles. References
It illustrates a single pole, double-throw (SPDT) device. Descriptions from the patent text are as follows: Fig. 1 - device shown in nonoperated position Fig. 2 - device shown in operated position Fig. 3 - cross-section 1 - glass envelope 2 - terminal 3 - resilient magnetic member 4 - non-magnetic member 5 - conducting member 6 - magnetic member
The UART usually does not directly generate or receive the external signals used between different items of equipment. Separate interface devices are used to convert the logic level signals of the UART to and from the external signaling levels, which may be standardized voltage levels, current levels, or other signals.
2) a rotary version of a multipole slide switch where one signal has a choice between multiple connections, such as SPDT, SP3T, SP4T. The DIP switch package also has socket pins or mounting leads to provide an electrical path from the switch contacts to the circuit board.
