The present invention discloses a bi-power automatic transfer switch with microswitches. The bi-power automatic transfer switch comprises a base plate, a galvanized box, a power mechanism, a left pushing pendulum, a right pushing pendulum, a bracket, a first microswitch and a second microswitch, wherein the galvanized box is mounted on the base plate, the power mechanism, the left pushing pendulum, the right pushing pendulum and the bracket are mounted on the galvanized box, the first microswitch and the second microswitch are mounted on the bracket, and the first microswitch and the second microswitch are connected in series with the motor in the power mechanism. Compared with the prior art, the bi-power automatic transfer switch is characterized in that two microswitches are provided to replace auxiliary contacts, thereby greatly reducing the production cost. During installation of auxiliary contacts, the switch has to be disassembled, which is time-consuming and labor-consuming. Micro switches are easy to install, work efficiency can be improved, and the needs of users can be met. The bi-power automatic transfer switch is easy to promote and apply in the industry.
Description
technical field [0001] The invention relates to the field of production of a dual-power automatic switching switch, in particular to the production of a dual-power automatic switching switch with a micro switch. Background technique [0002] Dual power supply automatic transfer switch refers to: a device controlled by a microprocessor and used for starting and switching between grid power and grid power, or grid power and generator power supply in the grid system, which can make the power supply continuous source power supply. Series dual power supply, when the common power supply suddenly fails or fails, it will automatically switch to the backup power supply through the dual power supply switching switch, so that the equipment can still operate normally. The most common ones are elevators, fire protection, monitoring, lighting, etc. [0003] In the existing dual power supply products, in order to control the opening and closing of the executive circuit breaker, auxiliary ...
