Index Heavy-Duty Pressure Switches available from Norman G Clark

Index Heavy-Duty Pressure Switches

The Index Heavy-Duty Pressure Switches, available from Norman G Clark , are suitable for a wide range of heavy vehicle and equipment applications where durability and reliability are crucial.

The Index Heavy-Duty Pressure Switches can withstand the shock and vibration of harsh under-hood and off-road conditions.

The Index Heavy-Duty Pressure Switches put up a double line of defence against vibration with two snap-action elements.

A crisp-response pressure disc triggers a Honeywell Micro Switch, assuring clean electrical switching. Both elements are real workhorses in high duty-cycle applications, lasting up to 1 million cycles or more.

OEM customers help to learn exactly how a pressure switch functions in the vehicle or machine. What are optimum set and reset pressures, what receives the switch signal output and what is done with that information are all important. Then the optimum specs can be dialled to help the entire system work at its best.

There are more options than just On-Off switching. The Index Heavy-Duty Pressure Switches allow the equipment to ignore a normal, momentary high pressure spike or low pressure dip. With Index Diagnostic Switches, the control computer can distinguish a wire short or a break from a normally-operating open or closed switched circuit.

Index Heavy-Duty Pressure Switches provide the following:

• Better vibration resistance
• Long life - up to 1,000,000 cycles
• Special time delay and diagnostic features available
• Custom-specifiable set and reset pressures
• Tight tolerances where high precision is needed
• Stable, drift-free calibration
• Choice of fittings and connectors
