The Basics of a Bolted Pressure Switch

A bolted pressure switch is a heavy-duty switch and it is used in the operation of power equipment. A bolted pressure switch is often the main disconnect for a facility. Some of the basic function, design, requirements for maintenance, and testing methods for bolted pressure switches are described here.

Function of a Bolted Pressure Switch

A bolted pressure switch is designed to shut off the power unit after the cycle is complete. The electrical circuit is broken when pressure is applied to the bolted pressure switch. Bolted pressure switches can be found in the switchboard. It runs automatically, with high pressure being put on the blade when the switch is closed. The only things that have to be done manually for a bolted pressure switch are maintenance and testing.

The Design For a Bolted Pressure Switch

They can be made out of stainless steel. A bolted pressure switch comes in 800, 1200, 1600, 2000, 2500, 3000, or 4000 amperes. The amperes rating are the unit of measurement for the electrical current and energy flowing through the electrical wires to a device or an appliance. They can be picked by certain specifications. A bolted pressure switch is chosen by identifying the correct switch point range, deadband, and accuracy. It is a knife-type switch in design.
