Described rotating assembly 5 coordinates with the circular hole at pedestal 1 two ends, and the axial one end of rotating assembly 5 is fixing by spring cotter 15, and the other end is fixed by the boss of rotating assembly 5, ensures its axially not transmission;
On described pedestal 1, be provided with the pad 16 can surface anodization layer scratching for preventing.
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.In the time there is major accident or the uncontrollable state of aviator in aircraft, aviator's trigger switch makes travel switch startup work, axially master cock signal is switched in transmission within the utmost point short time, controls follow up device pilot seat realization is launched, and aviator is escaped.
It is axial transmission that described travel switch has been realized by bar transmission, conversion, and conversion process axis rotates without hindrance smoothly, and actv. is by the disconnection of contact disk control master cock.
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 are effective; The way of output is adaptor union, facilitates auxiliary equipment docking; Take spring control rotor, cause that product synchronism is good, transfer time is little; The excellent performance that possesses skills, can be 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.
