Stroke switch with remote control reset function

Abstract

The invention discloses a stroke switch with a remote control reset function, which comprises a shell body, a core part module, an electromagnetic valve, a plunger and a seal sleeve. The core part module and the electromagnetic valve are sequentially arranged in the inner cavity of the shell body; a push rod on the electromagnetic valve is jacked on the slow transmission rod of the core part module; the seal sleeve is sleeved on one end of the shell body; the plunger movably penetrates through the through hole of the seal sleeve; the outer end of the plunger goes out of the seal sleeve; and the inner end of the plunger is connected with one end of the slow transmission rod on the core part module which is fixedly connected with an armature. The stroke switch with the remote control reset function is provided with the core part module and the electromagnetic valve; the push rod on the electromagnetic valve is inserted and buckled on one end of the slow transmission rod on the core part module; the other end of the slow transmission rod is over against the plunger; and the push rod on the electromagnetic valve can drive the slow transmission rod to move back and forth in a core part shell, so that the spring force of a movable rod spring is overcome, a permanent magnet and the armature are close and are actuated and the plunger is reset. Because the electromagnetic valve can be controlled remotely, so that the stroke switch has the remote control reset function.

Description

technical field

[0001] The invention relates to an electrical control part, in particular to a travel switch with a remote control reset function. Background technique

[0002] The travel switch is a commonly used small current master electrical appliance. It is an electrical appliance that switches circuits according to the travel position of the moving parts. It uses the collision of the moving parts of the production machinery to make the contacts move to realize the connection or break of the control circuit. To achieve a certain purpose of control. Most of the resets of conventional travel switches are carried out by manual reset. For some travel switches installed in high positions or other places that are difficult to reach, the reset becomes quite difficult. Therefore, the industry is in urgent need of a travel switch that can realize remote control and reset. Contents of the invention

[0003] The object of the present invention is to provide a travel switch wit...
