Described rotating assembly 5 coordinates with the circular hole at pedestal 1 two ends, and the axial one end of rotating assembly 5 is fixed by spring cotter 15, and the other end is fixed by the boss of rotating assembly 5, ensures its axially not transmission;
Described pedestal 1 is provided with for prevent can surface anodization layer scratch pad 16.
Described travel switch can be arranged in aircraft seat ejection life saving system, is axial transmission by bar transmission, conversion, then by the disconnection of contact disk master cock.When there is major accident or the uncontrollable state of aviator in aircraft, aviator's trigger switch makes travel switch startup work, axial transmission switches master cock signal in very short time, controls follow up device and makes pilot seat realize launching, aviator is escaped.
It is axial transmission that described travel switch achieves by bar transmission, conversion, and conversion process central axis is without hindrance smoothly, and actv. controls the disconnection of master cock by contact disk.
Described travel switch volume is little, quality is little; Simple metal shell, shielding, good sealing effect, affect without height change; Each part reliability is very high, and shock-resistant, vibration, acceleration/accel is effective; The way of output is adaptor union, facilitates auxiliary equipment to dock; Take spring to control rotor, cause that product synchronism is good, transfer time is little; Possess skills excellent performance, can between-55 DEG C ~+70 DEG C the advantage such as use; Belong to electromechanical integrated product; There is comparatively huge economic value and social value.
