Goldtech Controls Limited is a company focused on pressure switch and other appliance control solutions. The company’s Series PS-100 air-pressure switches feature customer-specified fixed set points or field-adjustable set point between 0.10 and 5.0 in w.c. They are specifically designed for OEM markets. They are used to sense positive or negative air pressure and are equipped with various sample line connections, terminal styles, and mounting arrangements.

A sensitive, high-reliability snap-action switch is used as the main switching element. The snap-action switch can provide a high switching capability up to 5 A 125/250 V a.c.

The main pressure-sensing diaphragm is made of post-cured material, which guarantees the fixed set points being constant in different working environment and gives a longer lifetime. The typical applications of PS-100 series pressure switch include boilers, hot water heaters, HVAC equipment, home appliances, and other industrial equipment.

Series PS-200 pressure switches are designed with wide range of set points from 5 to 100 in w.c.; fixed set point or field adjustable set point are available. PS-200 pressure switches can act as electrical safety protection switches where water is used in conjunction with electricity such as swimming pools, spas, hot tubs, and sanitary equipment, outdoor machines, medical equipment, or industrial controls; except this, they could be used together with an air button for remote control purpose.

The Series PS-300 incorporates a new compact design and is well suited to today’s low- and mid-range clothes washers and dishwashers requiring single level control. It is also suitable for the use with either hybrid or full electronic controls. The switch allows quick installation and combines with high performance for accurate fills to ensure low water level and energy consumption, with overflow and dry heater safety. PS-300 features the set point of makes pressure and breaks pressure from 25 to 400 mm w.c. and 10 to 350 mm w.c., respectively. The differential pressure is from minimum 10 mm w.c. to maximum 130 mm w.c. A snap-action mechanism is also adopted and can provide electrical ratings up to 16(4) A 250 V.
