Overview

FEATURES

SPDT DC Contactor(Single Pole Double Throw DC Contactor) is an electrical switching device mainly used in DC circuits. The SPDT in its name stands for Single Pole Double Throw, which means that the contactor has one input terminal and two output terminals.

Applications:

– Motor control: used for forward and reverse control of the motor, and the motor can be reversed by switching the circuit direction.

– Source switching: In situations where switching between two power sources is required, such as backup power systems.

– Signal switching: In automation systems, used for signal selection and switching.

– Lighting control: In the lighting system, it can be used to control the switches of different lights.

SPDT DC contactor is a flexible and efficient electrical device suitable for a variety of DC circuit control occasions.
