Finger spring is a new type of electrical connection method for the high-voltage switch profession, which has the advantages of simple structure, convenient equipment, strong flow ability, cost saving, etc., and is applied to turn off the combined electrical appliances, which can greatly reduce the labor intensity and production cost.

1. Simple structure, small size, less materials, low cost; Satisfactory device planning space small scale requirements, suitable for compact planning; The small number of parts simplifies the planning of connecting devices

2, multi-point contact, high concentration, can complete almost no loss contact. Ensure a large ampacity; Good electrical conductivity, high electrical and thermal stability.

3. The contact pressure of each contact point is not high, and it has good wear resistance.

4, together the structure makes it have a wide working range; Promise that there should be a large public service in the contact surface; It has greater adaptability to processing errors and device errors, and is more suitable for large-scale production.
