YM702 Pressure switch is designed according to the structure of enduring high pressure , and it can stand 5-10 times impact of highest pressure range.

The YM20 pressure switch is specifically designed to stand up to extended duty applications. This switch is factory set but capable of field adjustment. It features a Kapton diaphragm for compatibility with a wide variety of fluids, and various terminations including a Metri-Pack connector that forms a tight seal when connected. Among the outstanding design benefits are its durable construction, compact size, and enhanced set point integrity.

The YM30 employs a differential pressure to actuate a precision micro switch at a chosen pressure setting. This may be the difference between atmospheric and a negative or positive pressure or between any two given pressures. When a change of pressure occurs between the negative pressure chamber and the positive pressure chamber, the main diaphragm activates the micro switch at a pre-determ value.
