Abstract

The invention discloses a seal stroke switch which consists of a tower-form contact system of a seal structure, a pedestal combination, an outer hood, an axle and a guide wheel. One end of a push cylinder and one end of the periphery of a base are respectively manufactured into an interface form suitable for welding; the left end and the right end of a welding sylphon bellows are respectively fused together with the push cylinder and the base by welding, so as to form the seal shell of the stroke switch; L-shaped contact sheets and supporting sheets are overlapped together and are riveted in the annular step hole of the pedestal by rivets; every two mutually symmetrical contact sheets form a contact quadrangle and a tower-form contact system; the middle of the pedestal is provided with a through hole; the pedestal combination and a glass isolator are sintered together by the induction terminal of a basic board; one end of the pedestal combination is welded with a connection terminal and the other end is welded with the induction terminal of the pedestal combination, thus improving the seal performance and the reliability of the stroke switch.

Description

1. Technical field [0001] The invention belongs to the field of switch actuators, in particular to a sealed stroke switch. 2. Background technology [0002] With the rapid development of the complete machine system, the storage period is required to be longer and the reliability is higher and higher. This makes the limit switch used in the original whole machine system unable to meet the requirements of its ultra-long storage period and high reliability because it does not have sealing requirements. Therefore, the present invention provides a sealed travel switch that can be used in the complete machine system. The travel switch has a fully welded sealing structure, which can meet the requirements of harsh environments and long-term storage. 3. Contents of the invention [0003] The object of the present invention is to provide a travel switch for detecting the position and state of an aircraft, usually the travel switch is compressed and in a normally open state. During...
