Pressure type temperature controller with sealed switch box

The invention discloses a pressure type temperature controller with a sealed switch box. The pressure type temperature controller comprises a switch box assembly, a corrugated pipe assembly, a body assembly and the like. The switch box assembly is provided with a rubber diaphragm with a corrugated film structure, the peripheral edge of the rubber diaphragm is fixedly sealed with a partition plate,a central head of the rubber diaphragm sleeves a seal section of a push rod and is sealed on the seal section of the push rod, and accordingly air-tight seal can be implemented without influence on normal actions of the push rod. The pressure type temperature controller has the advantages of small volume, low cost and reliable and durable seal, and is particularly suitable to be applied to explosion-proof places with requirements on pressure type temperature controllers with high rated currents (such as 25A). 种开关盒密封的压力式温控器，由开关盒组件、波纹管组件、主体组件等组成，其中开关盒组件设有块带波纹膜结构的橡胶膜片，四周边与开关盒和隔热固定密封，其中心头部套入并密封在推杆的密封段上，实现了气密性密封而又不影响推杆的正常
