1. Requirement Analysis

As a kitchen appliance, the core requirements for microswitches in Joyoung pressure cookers include:

Safety in high-pressure environments: The switches must withstand high temperatures and pressures to prevent failure and potential safety hazards.

Frequent mechanical operations: The lid opening/closing and pressure valve actions require switches with a high lifespan (typically over tens of thousands of cycles).

Waterproof and oil-resistant: The kitchen environment demands switches with strong sealing properties.

Precise triggering: Ensuring the reliability of functions such as pressure control and power-off protection.

2. Solution

(1) Product Selection and Technical Compatibility

Model: ZingEar Micro Switch G6 series switches are used, featuring oil resistance and high temperature resistance.

Contact Material: Silver alloy contacts with low contact resistance and arc resistance ensure stability under frequent power cycling in high-pressure cookers.

High Mechanical Lifespan: Designed for an ultra-long lifespan (e.g., over 500,000 cycles), suitable for the lid being opened and closed multiple times daily.

(2) Safety Redundancy Design

Dual Power Cutoff Protection: The microswitch is linked with a pressure sensor; when abnormal pressure or temperature is detected, power is immediately cut off.

High-temperature resistant materials: The housing is made of flame-retardant PBT or nylon material, and the internal springs are high-temperature resistant and do not deform.

(3) Customized services

Structural adaptation: Customized switch travel and force based on the mechanical structure of the Joyoung pressure cooker (such as the lid locking mechanism).

Interface optimization: Provides terminal welding or plug-in connections to simplify the assembly process on the production line.
