The invention discloses a double-throw load switch comprising a front fixed plate, a rear fixed plate, a first box body side plate, a second box body side plate, a first opening spring, a second opening spring, a first support member, a second support member, a third support member, a first main switch contact, a second main switch contact, and a third main switch contact. To be specific, the first box body side plate and the second box body side plate are arranged at the outer side of the rear fixed plate; one end of the first opening spring is fixed at a first grounding operation shaft and the other end is fixed at the first box body side plate; one end of the second opening spring is fixed at a second grounding operation shaft and the other end is fixed at the second box body side plate; the first support member, the second support member and the third support member are arranged between the front fixed plate and the rear fixed plate; the first main switch contact is fixed at the third support member; the second main switch contact is fixed at the first support member; and the third main switch contact is fixed at the second support member. According to the invention, the effect of improvement of switching reliability of the dual power supply is realized.
Description
technical field [0001] The invention relates to the field of switches, in particular to a double-throw load switch. Background technique [0002] With the development of the national economy, the reliability of power supply has become a factor that people value in practice, and there are higher and higher requirements for the reliability of power supply. [0003] In electrical loads, three-level loads generally allow a single power supply, and in the case of dual power supplies, the dual power supplies are mutually backup. When the power supply fails and loses power, the important load whose power supply is stopped is switched to another power supply to ensure that the load continues to receive power. In engineering, two or more power supplies should be provided for loads that are not allowed to be interrupted. Reliable switching between two power supplies is particularly important for power supply reliability. [0004] At present, in the dual power supply, two load switch...
