12×12 Waterproof Tactile Switch

12*12 Tact Switches Display

Product structure of 12×12 waterproof tact switch

The product structure of 12×12 waterproof flick switch usually includes the following key parts:

Insert: the insert is the fixed part inside the switch, which is used to support and fix other components.

Base: The base is the main part of the switch, which provides a mounting platform for other components and serves as support and protection.

Shrapnel: The shrapnel is the core part of the switch, which realizes the on-off of the circuit through the change of force of the metal shrapnel. In waterproof flick switches, a layer of polyimide film is usually added to the shrapnel to enhance its waterproof performance.

Pushbutton: The pushbutton is the part of the switch that the user interacts with, and the switch action is triggered by pressing the pushbutton. Pushbuttons are usually designed with ergonomics and aesthetics in mind.

Cover: The cover covers the top of the switch for protection and decoration. In waterproof flick switches, the cover plate usually adopts a sealed design to ensure the waterproof performance of the switch.

Working principle of 12×12 waterproof tactile switch

The working principle of 12×12 waterproof flick switch is based on the momentary conduction of mechanical contact. When the user gently presses the switch's button, the button moves down and compresses the shrapnel, causing the contacts on the shrapnel to make momentary contact with the contacts on the base, thus conduction of the circuit. When the pressure is withdrawn, the shrapnel will return to its original state, the contacts will separate, and the circuit will be broken.

The working principle of the waterproof flick switch can be summarized in the following steps:

Pressing the button: the user applies a certain amount of pressure on the button.

Contact contact: the button moves down and compresses the shrapnel so that the contacts on the shrapnel make contact with the contacts on the base.

Circuit conduction: when the contacts make contact, the circuit is conduced and current can flow through the switch.

Withdrawal of pressure: When the user withdraws the pressure applied to the button, the shrapnel returns to its original state and the contacts separate.

Circuit break: After the contacts separate, the circuit is broken and current can no longer flow through the switch.

In addition, the waterproof flick switch is sealed by multi-layer sealing design, such as cover sealing, shrapnel sealing, etc., to ensure that water, dust and other external substances cannot intrude into the inside of the switch, so as to ensure its waterproof performance and long-term stability.
