Product Overview: HOSONG 16mm flat head non-illuminated metal push button is a cost-effective basic industrial control component. With a minimalist flat round head and no LED structure, it features fewer internal parts and ultra-low failure rate. Equipped with 1NO1NC composite contacts and dual momentary/latching modes, it is rated 3A/AC220V. The fully sealed brass chrome-plated/stainless steel housing achieves IP67 waterproof and IK10 impact resistance, ideal for mass standardized assembly and basic equipment control.

Core Parameters: Brand: HOSONG; Model: HS16A-P11□/◎; Mounting Hole: Φ16mm; Head Type: Flat Round; Contact: 1NO1NC; Operation Mode: Momentary/Latching; Light Type: Non-illuminated; Rating: 3A/AC220V; Protection: IP67, IK10; Certifications: CCC, CE, RoHS.

Product Advantages: 1. Simplified structure ensures stable performance in dusty and low-temperature environments; 2. Dual contacts support dual-channel control signal output for industrial logic systems; 3. Universal 16mm hole size for direct replacement without panel modification; 4. Sealed metal housing prevents water, oil and dust intrusion; 5. High cost performance for mass equipment assembly.

Application Scenarios: Suitable for production line reset and jog control, industrial cabinet manual operation, material conveying equipment switching, laboratory non-standard test jigs, photovoltaic auxiliary equipment and general electromechanical equipment control.

FAQ

Q1: Can lights be installed later?
A: No, the integrated sealed structure does not support post-installation of lights. Please choose illuminated models if needed.

Q2: Can it drive contactor coils directly?
A: It can drive small-current contactors directly. Intermediate relays are recommended for high-power contactors.

Q3: Is the stainless steel version suitable for oily workshops?
A: Yes, it is oil and oxidation resistant for long-term use in harsh industrial environments.

Customer Case: A non-standard automation manufacturer in Foshan adopted HOSONG 16mm flat non-illuminated buttons for mass reset and jog control. The procurement cost was reduced by 20%, and equipment failure rate dropped by 80%. The company purchases more than 20,000 pieces annually with significantly reduced after-sales maintenance costs.
