Embodiment Construction

[0017] As shown in the figure, a physically separated stroke control switch includes a housing 1 and a button 2. The housing 1 has a housing cavity, and a pin and a socket are arranged in the housing space. The housing 1 is also provided with a button installation hole 101 communicating with the accommodation cavity, the button 2 is penetrated in the button installation hole 101, one end of the button 2 protrudes from the casing 1, and the button 2 and the casing 1 are connected by a poly-four Fluorine gasket sliding seal. The cavity of the housing 1 is also provided with a socket insulator 3, the socket insulator 3 is fixed in the housing 1 through the cover plate 9, and the cover plate 9 and the housing 1 are sealed by a rubber gasket, so that The product has extremely high vibration resistance, pressure resistance and environmental resistance requirements. The socket insulator 3 has a cavity and one end is open. The opening of the socket insulator 3 is provided with an ins...

Abstract

The invention relates to a physical separation type stroke control switch. The physical separation type stroke control switch comprises a shell and a button, wherein the shell is provided with an accommodating cavity, an insertion pin piece and an insertion hole piece are arranged in the accommodating cavity, a button installation hole which is communicated with the accommodating cavity is further formed in the shell, the button is arranged in the button installation hole in a penetrating mode, a socket insulator is further arranged in the cavity of the shell, the socket insulator is provided with an accommodating cavity, one end of the socket insulator is open, an insulating pressing plate is arranged at the position of the opening of the socket insulator, the insulating pressing plate is provided with an ejector rod through hole and two insertion pin through holes, and two guide rods are arranged in the cavity of the socket insulator. According to the physical separation type stroke control switch, reliable signal connection of a product within a certain stroke can be guaranteed, reliable signal disconnection can be achieved beyond the stroke, the insertion pin piece is guided by a guide pin of the socket insulator all the time during the whole stroke, and smooth connection and smooth disconnection of signals can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of control switches, in particular to a physical separation stroke control switch. Background technique [0002] The stroke control switch is also called a position switch or a limit switch. Its working principle is to use the collision of mechanical moving parts to make its contacts move to realize the connection or break of the control circuit to achieve a certain control purpose. The stroke control switch has a wide range of uses in the field of electrical technology. The stroke control switch is installed in a pre-arranged position. When the module mounted on the mechanical moving part hits the stroke switch, the contact of the stroke switch will move to realize the switching of the circuit. Traditional switches can realize the on-off function, but the stroke is not obvious, and most of them are contact switches, which cannot be used for reliable control. Contents of the invention [0003] The purpo...
