A double-pole, single-throw (DPST) switch is designed to simultaneously open or close two electrically independent circuits using a single mechanical actuator.

Cevap: Cevap

Cevap

True. A DPST switch controls two isolated circuit paths simultaneously with a single actuator mechanism.
The statement accurately defines a DPST switch. In electrical engineering and electronics, 'pole' refers to the number of separate circuits controlled by the switch, and 'throw' refers to the number of closed contact positions available per pole. A DPST switch therefore controls two separate circuits with a single ON/OFF throw action.

Adım Adım Çözüm

1
Analyze the switch terminology for poles and throws.
'Double-pole' (DP) signifies two separate, electrically isolated circuits or lines being controlled, while 'single-throw' (ST) indicates that each pole has only one active closed position (ON/OFF).
Understanding standard electrical switch nomenclature is necessary to identify contact arrangements.
2
Evaluate the mechanical and electrical operation of the switch.
The two internal sets of contacts move in unison via one toggle or lever, switching both independent circuits at the same instant.
A single mechanical linkage operates both poles together to ensure simultaneous opening or closing.
