Security controller

Abstract

The invention discloses a security controller comprising a winding, a movable contact spring, a contact inserting sheet, a core shaft, an arc-shaped ring, a framework, a suction sheet, a shell and a base. The winding is wound on the framework, and is sleeved on the core shaft with the framework; a groove is arranged at the top of the core shaft; the arc-shaped ring is pressed in the groove; a supporting corner is arranged between the base and the core shaft; a movable resistant core is arranged between the movable contact spring and the contact inserting sheet; a wire base is arranged below the contact inserting sheet; the movable contact spring, a resetting spring, the movable resistant core, the contact inserting sheet and the wire base are located in the shell; the contact inserting sheet is provided with a normally-opened piece and a normally-closed piece; a push button is arranged above the suction sheet; a pressure spring is arranged between the push button and the suction sheet; the pressure spring and the push button are inserted into a panel together; and the resetting spring is arranged below the panel. The security controller provided by the invention is of a positive and negative direction operation structure, so that the error action is avoided and the reliable operation can be realized. The movable contact is of a magnetic combination structure, so that the security controller has the advantages of dust and moisture prevention, good arc extinction property, small size and the like.

Description

technical field [0001] The invention relates to a controller, in particular to a KJD safety controller. Background technique [0002] The mechanical controllers currently on the market are movable up and down, and the bottom is fixed.
