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.
