Panel membrane switch for inverter

Abstract

The invention belongs to the technical field of membrane switches, and discloses a panel membrane switch for an inverter. The panel membrane switch comprises a panel, an upper conducting layer, a lower conducting layer and an insulation isolation layer, the insulation isolation layer is clamped between the upper conducting layer and the lower conducting layer, the panel is adhered to one side, deviating from the lower conducting layer, of the upper conducting layer, an arc-shaped reed is embedded in the upper conducting layer, one side, facing the lower conducting layer, of the arc-shaped reed is integrally connected with a moving contact perpendicular to the lower conducting layer, a trigger groove is formed in the position, corresponding to the moving contact, of the lower conducting layer, an elastic conducting thin film is sealed at the top of the trigger groove, and the moving contact abuts against the elastic conducting thin film or keeps a distance from the elastic conducting thin film; and triggering pieces are included and arranged on the arc-shaped reed, are symmetrically arranged on the two sides of the moving contact, and are used for conducting the upper conducting layer and the lower conducting layer. The membrane switch is simple and stable in structure, good in pressing hand feeling and long in service life.

Description

technical field [0001] The invention belongs to the technical field of membrane switches, and in particular relates to a panel membrane switch for inverters. Background technique [0002] The membrane switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: the panel, the upper circuit, the isolation layer, and the lower circuit. The point is deformed downward, and the contact with the pole plate of the lower circuit is conducted. After the finger is released, the contact of the upper circuit bounces back, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has a rigorous structure, beautiful appearance, good sealing, and has It is widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, smart toys, household appliances and other fields. [0003] Membrane switches can improve the feel of equip...

AI Technical Summary

Problems solved by technology

[0003] Membrane switches can improve the feel and sense of technology of equipment and instrument control. Generally, they are usually turned on by pressing down on the reed. Membrane switches applied to inverters in the prior art are accompanied by frequent electrical switching operations and multiple The following problems often exist in repeated pressing: the structure of the membrane switch is deformed and loses its elasticity; the pressing feel is poor, which affects the electrical operation of equipment and meters; the switch stroke structure is complex and the manufacturing cost is high
