Product Overview

The HOSONG 22mm momentary push button is a highly versatile basic control switch for industrial fields. Adopting a standard Φ22mm mounting hole, it is compatible with most industrial control panels, automation equipment and electrical cabinets. Designed with an automatic reset structure, it triggers signals when pressed and rebounds automatically after release, perfectly suited for inching control, signal triggering and equipment debugging. Equipped with a reinforced metal housing and high-durability silver alloy contacts, it features crisp and stable rebound feedback, arc resistance and ultra-low failure rate, serving as a standard basic component for various electromechanical equipment.

Product Advantages

1. Pure momentary mechanical structure with simple and intuitive operation, avoiding safety risks such as accidental locking; 2. Sensitive rebound design ensures fast response for high-frequency inching debugging and instantaneous triggering; 3. Universal 22mm hole size achieves full compatibility for easy equipment replacement and matching; 4. Thickened silver alloy contacts resist arc oxidation with a million-cycle service life and stable conduction; 5. Dustproof and moisture-proof sealed structure adapts to long-term operation in conventional indoor industrial environments.

Application Scenarios

Inching debugging and instantaneous start-stop control of automation equipment; manual signal triggering and process reset keys for industrial production lines; auxiliary inching switches and debugging keys for electric control cabinets; instantaneous start and reset operation panels for small and medium electromechanical equipment; manual intervention and program trigger control for non-standard automation equipment; basic control keys for teaching training and small industrial control equipment.

FAQ

Q1: Can the momentary button be kept pressed for long-term power-on? A: It supports short-term pressing power-on, but is not suitable for long-term continuous power supply. Latching buttons are recommended for such working conditions.

Q2: Will rebound failure occur after frequent inching operation? A: Built-in thickened rebound spring and reinforced transmission structure provide excellent fatigue resistance without jamming or failure after millions of high-frequency operations.

Q3: Can it be modified to an illuminated version? A: It can be directly replaced with the same specification illuminated momentary button with fully universal mounting size without panel modification.

Customer Case

An automation accessory manufacturer in Suzhou supports basic control keys for small and medium assembly line equipment. Ordinary buttons suffered from rebound jamming and short service life. After adopting HOSONG 22mm momentary buttons, the equipment button failure rate dropped by 85% and after-sales complaints were greatly reduced. The annual stable purchase volume reaches 12,000 pieces as the standard matching key for all equipment.
