Product Overview

HOSONG 22mm flat non-illuminated metal push button is a standard large-hole control component widely adopted for heavy-duty automation equipment and industrial control cabinets. Designed with integrated flat round head and non-LED structure, it features simplified internal structure with high stability. Equipped with 1NO1NC composite contacts, it supports both momentary jog and latching hold operation, rated at 3A AC220V. Available in chrome-plated brass and 304 stainless steel housing, it is IP67 waterproof & dustproof, IK10 impact resistant with mechanical life up to 1 million cycles. Cost-effective and universally interchangeable, it serves as a basic industrial switch for equipment start-stop, reset and jog debugging, ideal for panel renovation of heavy machinery.

Core Parameters

Product Advantages

1. Largest standard 22mm mounting hole with large pressing area, anti-slip and anti-misoperation for operators wearing thick labor gloves;
2. Simplified non-light structure with fewer internal parts, lower failure rate in dusty, low-temperature and oily harsh environments;
3. Dual composite contacts transmit two separate signals to PLC for start-stop and fault feedback logic control;
4. Two housing options resist moisture and corrosion, long-term rust-free service in misty & oily machine shop environments;
5. Universal 22mm hole size enables direct replacement for old equipment without secondary hole drilling, lowering assembly expense.

Application Scenarios

1. Reset & jog buttons for large CNC machine tools and gantry machining centers
2. Start-stop control for heavy automatic production lines and auto-parts assembly lines
3. Manual operation buttons for high-power electric control cabinets and low-voltage distribution boxes
4. Auxiliary control circuits for large energy storage power stations and photovoltaic inverter cabinets
5. Control panels for injection molding machines, hydraulic equipment and construction machinery
6. Debugging and emergency bypass reset buttons for non-standard heavy-duty equipment

FAQ

Q1: Can an indicator light be retrofitted later? A: This is an integrated sealed structure with no reserved space for modification. Please select illuminated models if status indication is required. Q2: Can 3A contacts drive contactor coils directly? A: It works for small-power coils; intermediate relay is recommended for high-power contactors to extend contact service life. Q3: Is stainless steel version suitable for pickling workshops? A: It works well in ordinary oily & humid workshops; special corrosion-resistant models are recommended for strong acid & alkali environments.

Customer Case

A large auto-parts automation equipment manufacturer in Dongguan uses massive reset and jog buttons without light requirement across production lines. After bulk purchasing HOSONG 22mm flat non-illuminated buttons, unit procurement cost dropped by 18% while button failure rate decreased by 77%. With annual order volume of 22,000 pieces, equipment stability is improved obviously and after-sales maintenance frequency is greatly reduced.
