SU913469A1 - Push-button control station - Google Patents

Description

The invention relates to electrical engineering and can be applied in automated control systems.

Known push-button control, containing the base, switching devices mounted on the base, and the drive mechanism, which includes the plunger, a sleeve covering the plunger, balls, return spring, the working spring and the button [1]. '

The known device is complicated in design and not technologically advanced.

Also known is a push-button control post containing a base, a switching device mounted on the base and a drive mechanism comprising a pusher, an intermediate element fixed on the pusher, a sleeve covering the pusher, at least one ball, a return spring abutting the switching body apparatus, a working spring and a button located outside the base [21.

The known device has a complex structure.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that in a push-button control station containing ^{5 a} base / switching device mounted on the base and _{5 a} drive mechanism comprising a pusher, an intermediate element fixed on the pusher, a sleeve covering the pusher, at least one a ball, a return spring resting against the body of the switching apparatus, a working spring and a button placed at the bottom of the base, the sleeve is made with a face, and the ball is pressed against the sleeve with

side of its chamfer intermediate element by means of a return spring, while the button is fixed on

20 mentioned sleeve, and the working spring is placed inside the sleeve.

• In FIG. 1 and 2 shows the push-button control in two positions.

Push-button control, contains a switching device 1 with a drive element 2, mounted on the base 3 and the drive mechanism, which includes a pusher 4, covering his sleeve 5, at least

™ least one ball 6 return spring 3

four

7, the working spring 8, the button 9, placed outside the base 3 and connected to the sleeve 5, the intermediate element 10 in the form of a washer. At the end of the sleeve 5 in contact with the ball, the chamfer 11 is made. At the base, the groove 12 is made.

The device works as follows.

. When an external force acts on the button 9, the chamfer 11 displaces the ball 6 U into the groove 12 of the base 3. At the same time, the operating spring 8 presses the sleeve 5 to the intermediate element - washer 10, and the ball 6 is locked in the groove 12 of the base 3 by the outer wall of the sleeve 15 .

When unlocking the switched-on position of the switching device, it is necessary to remove from the base 3 the button-20 ku 9, compressing the working spring 8. When the space for the ball 6 between the sleeve 5 and the intermediate element U is cleared, all moving parts take the initial position under the action of the return spring 7.

Claims (1)

A button post control comprising a base, a switching device mounted on the base, and a drive mechanism comprising a pusher, an intermediate element fixed on the pusher, a sleeve covering the pusher, at least one ball, a return squad abutting the switching body apparatus, a working spring and a button placed outside the base, characterized in that, in order to simplify the design, the sleeve is made with a chamfer, and the ball is pressed against the sleeve from its chamfer side th element by means of return spring iri this button fixed to said sleeve, and the operating spring is arranged inside the sleeve.
