Membrane switch with novel structure

Abstract

The invention discloses a novel structure membrane switch, and the switch comprises a bottom shell; the top of the bottom shell is fixedly connected with a lower circuit, the top of the lower circuit is provided with a wire key, the top of the wire key is fixedly connected with an elastic sheet, the top of the elastic sheet is fixedly connected with a fixed layer, the top of the bottom shell is provided with an upper cover, and the upper cover is internally provided with a waterproof mechanism. The top of the upper cover is fixedly connected with a panel, the waterproof mechanism comprises a key, a sealing cover, a waterproof rubber ring, air holes, a sealing ring and a sealing gasket, the sealing cover is fixedly connected to the top of the key, the waterproof rubber ring is arranged at the top of the key, the air holes are formed in the axis positions of the key and the sealing cover respectively, and the sealing gasket is arranged in the sealing ring; the sealing ring is fixedly connected to the bottom of the inner wall of the key, and the sealing gasket is arranged at the top of the sealing ring. According to the technical scheme, the waterproof mechanism, the waterproof rubber ring sealing ring, the sealing gasket, the air hole and the like are arranged, so that the pressing hand feeling is guaranteed, and water is prevented from entering the membrane switch to cause rusting of the elastic piece.

Description

technical field [0001] The invention relates to the technical field of electrical switches, in particular to a membrane switch with a new structure. Background technique [0002] Membrane switch, also known as light-touch keyboard, adopts an integral sealing structure composed of flat multi-layers. A new type of electronic components, membrane switches are often used in medical equipment, electronic measuring instruments, smart toys, household appliances, etc., in some specific toys and other electronic measuring equipment, light-touch membrane switches are used. [0003] There are following defects or problems in the prior art: [0004] 1. Today’s membrane switches usually have holes reserved to ensure the pressing feel of the membrane switch. Moisture can easily enter the inside of the switch through the small holes, causing the membrane switch shrapnel to corrode and rust, and damage the switch; [0005] 2. When the current membrane switch is in use, the PET film on the...

Problems solved by technology

[0004] 1. Today’s membrane switches usually have holes reserved to ensure the pressing feel of the membrane switch. Moisture can easily enter the inside of the switch through the small holes, causing the membrane switch shrapnel to corrode and rust, and damage the switch;

[0005] 2. When the current membrane switch is in use, the PET film on the surface is easy to age when pressed, resulting in a bad switch feel and poor rebound effect
