Embodiment 1

[0017] The travel switch is composed as follows: the travel switch consists of a base 1, a support 2, an electrical connector 3, a spring 4, a shaft assembly 5, a block 6, a brake block 7, a piston 8, a post 9, a contact piece 10, Reed assembly 11, end cover 12; wherein: the support 2 is fixedly connected to the base 1, the electrical connector 3 is connected to the support 2, the rotating shaft assembly 5 is located inside the base 1, and one end of the spring 4 It is fixed on the base 1, and the other end is connected with the rotating shaft assembly 5. The spring 4 is used to limit the position and maintain the state, preventing vibration, shock, acceleration and other environmental products from automatically jumping. In addition, the spring 4 can accelerate the rotation of the rotor at the same time. Further reduce the state switching time; one end of the piston 8 is in contact with the shaft assembly 5, and the other end is the input end, which is driven by instantaneous ...

Abstract

The travel switch is composed as follows: the travel switch consists of a base (1), a support (2), an electrical connector (3), a spring (4), a rotating shaft assembly (5), a block (6), a brake block ( 7), piston (8), clamp (9), contact piece (10), reed assembly (11), end cover (12); wherein: the support (2) is fixedly connected to the base (1) Above, the electrical connector (3) is connected to the support (2), the shaft assembly (5) is located inside the base (1), and the travel switch is small in size and mass; the pure metal shell has shielding and sealing effects Good, no influence of height change; each component has high reliability, good impact resistance, vibration, and acceleration effect; the output mode is a connector, which is convenient for the docking of supporting parts; the spring is used to control the shaft assembly, resulting in good product synchronization and short conversion time; It has excellent technical performance and can be used between -55°C and +70°C.

Description

technical field [0001] The invention relates to the technical field of structural design and application of travel switches, and in particular provides a travel switch for aircraft seats. Background technique [0002] At present, aircraft products are rarely equipped with seat ejection life-saving systems. When an aircraft encounters an emergency, it is difficult for the pilot to leave the seat in a short time, which is a great threat to his life safety. [0003] People are eager to obtain a travel switch for aircraft seats with extremely short switching time and excellent technical effects. Contents of the invention [0004] The purpose of the present invention is to provide a travel switch with excellent technical effect. Realize that when a serious accident occurs to the aircraft, the pilot can escape by disconnecting the switch. [0005] The travel switch is composed as follows: the travel switch consists of a base 1, a support 2, an electrical connector 3, a spring ...
