An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

An example is a pushbutton switch. SPDT Form C [4] Single pole, double throw: Two-way: Three-way: A simple break-before-make changeover switch: C (COM, Common) is connected either to L1 or to L2. SPCO SPTT, c.o. Single pole changeover or single pole, centre off or single pole, triple throw Similar to SPDT.
These switches appear externally similar to single pole, single throw (SPST) switches, but have extra connections which allow a circuit to be controlled from multiple locations. Toggling the switch disconnects one "traveler" terminal and connects the other. Electrically, a typical "3-way" switch is a single pole, double throw (SPDT) switch. By ...

Circuit symbols of relays (C denotes the common terminal in SPDT and DPDT types.) Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can be thrown by energizing the coil. Normally open (NO) contacts connect the circuit when the relay is activated ...
Like other electrical switches, RF and microwave switches provide different configurations for many different applications. Below is a list of typical switch configurations and usage: Single pole, double throw (SPDT or 1:2) switches route signals from one input to two output paths. Single pole double throw (SPDT) switch from Agilent Technologies
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)
