Product Overview

The HOSONG 22mm flat-head non-illuminated push button is a minimalist universal control switch for industrial and commercial equipment with a standard Φ22mm mounting hole. The flat head creates an integrated and minimalist panel appearance, perfectly fitting flat and light-luxury equipment design styles. Adopting a pure circuit-free mechanical structure, it eliminates circuit loss and lamp aging faults with ultra-high stability, ideal for basic start-stop, inching and reset scenarios without lighting indication. Equipped with precision spring rebound and durable silver contacts, it delivers smooth and consistent pressing feel. The dust and moisture-proof metal sealed housing ensures long-term stable operation for commercial and light industrial equipment.

FAQ

Q1: Can lighting be added later? A: Fixed structure without light cavity. Please select the flat-head illuminated model if lighting is required.

Q2: Is flat design prone to misoperation? A: Flush flat design eliminates protruding misoperation risks with higher safety than convex and ball-head buttons.

Q3: Is latching mode available? A: Both momentary and latching versions are in stock to match different equipment control logic.

Customer Case
