SG-3 series pressure control switch is a mechanical pressure control device used to control the air compressor to automatically start and stop within the preset pressure value range. The device is flexible to install, easy to use, durable, and is usually set at the factory. It is closed and equipped with a relief valve to avoid starting the motor load, which is more energy-saving and environmentally friendly. The assembly with Bama assembly is convenient for users to install and use directly. Special specifications can be customized according to customer requirements.
