Touch finger spring is a new type of electrical connection method for high-voltage switchgear, which has the advantages of simple structure, convenient equipment, strong current carrying capacity, and cost saving. It is applied in closing combination electrical appliances, which can greatly reduce labor intensity and production costs.

1. Simple structure, small size, minimal materials used, and low cost; Satisfied with the requirement of small spatial scale in device planning, suitable for compact planning; The minimum number of components simplifies the planning of connecting devices

2. Multi point contact, high concentration force, can achieve almost zero loss contact. Ensure a large current carrying capacity; Good conductivity, high electrical and thermal stability.

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

4. The structure together provides it with a wide working range; Promise to have significant public service on the contact surface; Has greater adaptability to processing errors and device errors, and is more suitable for large-scale production.
