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

A travel switch comprises a substrate (1), a supporting seat (2), an electric connector (3), a spring (4), a rotating shaft component (5), a clamping block (6), a brake block (7), a piston (8), a clamping post (9), contact pieces (10), a spring plate component (11) and an end cover (12), wherein the supporting seat (2) is fixedly connected to the substrate (1), the electric connector (3) is connected with the supporting seat (2),and the rotating shaft component (5) is positioned on the inner side of the substrate (1). The travel switch has the advantages of small size and small mass; because a casing is totally made of metal, the shielding and sealing effects are good, and the travel switch is free from height change influence; the components have the advantages of higher reliability, shock resistance, vibration resistance, and good accelerating effect; outputting is performed by the connector, so that but joint with mating parts is facilitated; the spring is adopted for controlling the rotating shaft component, so that the synchronicity of the product is good, and the switching time is short; the technical performance is good, and the switch can be used at a temperature between minus 55 DEG C to 70 DEG 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 ...
