The SG-4 series pressure control switch is a mechanical pressure control device used to control the air compressor to automatically start and stop within a preset pressure value range. The device is flexible in installation, easy to use, and durable. The factory setting is usually normal It is closed and equipped with a load release valve to avoid starting the motor load. The circuit breaker with motor protection can prevent the motor from overloading, which is more energy-saving and environmentally friendly. Products with special specifications can be customized according to customer requirements.
