Environment in can reach the most long safety work used, break seat switches set is common technique, belongs to prior art.
Constant-voltage equipment of the prior art typically uses two kinds of patterns：When under static state, using shell fragment in itself
Elastic force is deformed to maintain long-term contact chucking power, although its conductive relatively better shortcoming of signal power source is to be long-term operation
After shell fragment is curved, chucking power declines, and influences safety work, or even cause the current operation field of security incident to cancel gradually；Second,
The contact strip that constant pressure break in dynamic state uses is processed into circle and is enclosed on the additional torsion spring of wiring screw rod and side spring to do
Axle motion maintains chucking power, and to ensure electrical contact, in actual use, frequent generation contact strip and power supply fully connect
Touch and certain potential safety hazard be present；Two kinds of contact strips in currently available technology do not find that the work longevity of 500,000 times can be surmounted
Life, control modern railways operation have a long way to go, and have a strong impact on safety work, or even cause security incident, torsion of the prior art
There is unsafe factor in spring and side spring device, become the fracture of XOR torsion spring as the torsion of torsion spring and side spring produces in different environments,
Have a strong impact on that the chucking power of contact strip forms loose contact, influence signal transmission, lead to very big railroad personnel's security incident.
