- Subminiature:A switch that is smaller than 25mm (1 inch) long.
- Surface Mounting (SMT):A method of soldering packages directly onto the surface of printed-circuit boards without insertion of the leads through hole in the board.
- Switch Abbreviations:SPST: Single-pole single-throw; SPDT: Single-pole double-throw; DPST: Double-pole single-throw; DPDT: Double-pole double-throw. (See also Forms). Please refer to the ITW Switches Characteristics/Circuits for more detail
- Tactile Feedback:The feel of increased or decreased force transmitted through the button or toggle of a switch when
- Terminal:The metal portion of a switch, exterior to the body, that is used to connect the switch to an electrical circuit.
- Throw:Denotes the number of different circuits that each individual pole can control.
- Total Travel:The distance that a button or actuator of a switch travels from the rest or un-operated position until the button stops after actuation.
- Transducer:A device that converts a mechanical input into an electrical output.
- Translucent:Transmitting light so that objects lying beyond cannot be seen distinctly.
- Transparent:Transmitting light so that objects lying beyond can be seen distinctly.
- Travel:The distance that a switch button moves between events like operate point, reset point or other point of interest when operating the switch.
- Trim Switch:A switch used to provide 2 or 4-way actuation - often up/down or up down/right left control.
- Trip Point:The position of the button or toggle of a switch when the switch operates.
- Truth Tables:The output code or connection sequence from a thumbwheel switch.
- Two Circuit:Refer to Form Z. Includes single pole, double throw and double break configurations.
