Pressure Switch

A543 Air Socket Switch is a remote control device that can be used in conjunction with pneumatic buttons for remote control purposes. Certifications: UL

The A542 Air Socket Switch is optimized for indoor use, stable and reliable, and can be remotely controlled by combining pneumatic buttons. It is specifically designed for safe and reliable use. Certifications: UL

A515 Thermostat is suitable for air conditioning units, refrigeration units, freeze-drying units, etc. The internal shrapnel structure ensures good performance of the switch. Comes with a temperature regulating fixed plate to prevent temperature changes.

The A514 Differential Pressure Switch features highly sensitive pressure sensors on both sides that trigger the switch mechanism to control equipment like motor-driven valves. It's typically used to manage pressure differences between supply and return pipes in water and oil systems. For example, it can control a valve in the bypass near the pump; when the pressure difference exceeds the set value, the valve opens or closes to maintain normal system operation. Certifications: UL

The A513 Pressure Switch is a single pole double throw switch that controls the ON/OFF action of the external circuit by detecting changes in pressure and changing the state of the internal switch. When the system pressure exceeds the set value, the micro switch will activate, cutting off the circuit to protect the system. Suitable for pressure control, pressure limiting, and alarm of non corrosive liquids, gases, and vapors.

The A512 Pressure Switch controls compressor pressure in refrigeration systems. Its internal micro switch ensures reliable performance and allows simultaneous control of high and low pressure levels. It comes with a standard mounting bracket. Certifications: UL
