Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 ~ Figure 4 As shown, the metal push button switch of the present invention includes a housing 1, a base 2 located at the bottom of the housing 1, a conductive terminal 3 inserted in the base 2 and a switch assembly 4 installed in the housing 1, the base 2 and the The shell 1 is connected, and also includes a brim 5 and a sealing ring. The shell 1 can extend into the brim 5 and be connected with the brim 5. The shell 1 is provided with an external thread 11, and the brim 5 matches the shell 1 and extends into the brim 5. Part of the external thread 11 is provided with an internal thread 51, and the shell 1 and the brim 5 are connected by a thread tight fit. The part of the shell 1 that does not extend into the brim 5 is not provided with a thread near the brim 5, and the part of the shell 1 that is not provided with a thread is matched. The thr...

Abstract

The invention relates to the technical field of switches, and particularly relates to a metal button switch. The switch comprises a housing, a base located at the bottom of the housing, a conductive terminal inserted into the base and a switch assembly arranged in the housing. The base is connected with the housing. The switch also comprises a brim and a sealing ring. The housing and the brim areconnected in a close fit mode through threads. A part, not extending into the brim, of the housing is not provided with threads close to the brim; the part, which is not provided with the thread, of the housing cooperates with the thread of a part, which does not extend into the brim, of the housing to form a groove; the sealing ring is arranged in the groove and is tightly attached to the bottomof the brim. The switch is divided into two parts, namely the housing and the brim; the housing and the brim are tightly matched through the threads, thereby guaranteeing that water cannot permeate into the switch from the joint of the housing and the button in a continuous water environment; in addition, the housing adopts a thread-free design close to the tail end of the brim and is externally provided with the sealing ring, water can be prevented from permeating into the switch from the roots of the threads after the switch is installed, and the waterproof performance of the switch is further improved.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a metal button switch. Background technique [0002] A switch is a commonly used electronic device that opens a circuit, interrupts current flow, or diverts it to other circuits. There are various types of switches on the market, such as rocker switches, push button switches, push button switches, rotary switches, and emergency stop switches. Among them, the push button switch cuts off and closes the circuit by pressing, and is widely used in the field of electronic devices. Among them, the button switch is usually a metal button switch. This type of switch is generally equipped with a metal outer cylinder, a cap, a light-transmitting ring, a waterproof ring, and a base. Usually, the inner wall ring of the metal outer cylinder is provided with a limiter. An annular groove for clamping the waterproof ring is formed between them, so that the waterproof ring is clamped and pressed...
