PC-SK2—female-thread pressure switch
The IBO PC-SK2 is a mechanical pressure switch for controlling the operation of a single-phase pump. It switches the pump on when system pressure falls to the set value and switches it off when the upper threshold is reached. The operating thresholds are set by the user with two screws, while the ¼" connection, available with an internal and external thread, allows the device to be connected to the installation in two ways.
Who is it for?
- Installers and plumbers—the ¼" internal and external thread provides flexibility when connecting the switch to an existing pipeline.
- Homeowners with their own water source—the switch maintains pressure within the set range, automating pump operation.
- Users of pressure-boosting sets—the device controls a pump working with a pressure tank.
- Allotment gardeners and farms—durable solution for everyday pump operation during water withdrawal.
Applications
The PC-SK2 is suitable for domestic and garden water systems with a single-phase pump operating with a pressure tank. The switch maintains water pressure between the set lower and upper thresholds and controls the pump as water is drawn. It is compatible with surface and submersible pumps.
The device responds to the pressure in the pipeline to which it is connected. In a domestic pressure-boosting system, the PC-SK2 230 V pressure switch keeps the pump operating within the set pressure range, adjusted to the installation’s needs.
PC-SK2 pressure switch features
The PC-SK2 operates with two settings—the pump switch-on pressure and switch-off pressure. They are factory-set to 1.4 and 2.8 bar, respectively, and both values are adjusted with two screws: screw A controls the switch-on threshold, while screw B controls the switch-off threshold. The adjustment range is from 1.2 to 5 bar, with a minimum switch-on pressure of 1.2 bar. The difference between the thresholds should be at least 1 bar to prevent the pump from cycling too frequently.
A feature that distinguishes the PC-SK2 is its ¼" connection, designed with both an internal and external thread. This allows the switch to be connected directly to various installation components without additional adapters. The device supports single-phase pumps drawing up to 12 A, including more powerful models than those used with basic pressure switches. The durable plastic housing protects the mechanism in typical water installation conditions.

Frequently asked questions (FAQ) – PC-SK2 pressure switch
What is the PC-SK2 pressure switch used for?
The PC-SK2 is a mechanical pressure switch that automatically switches the pump on and off depending on the water pressure in the system. It maintains the pressure between the set lower and upper thresholds, allowing the pump to operate without manual control.
What distinguishes the connection on the PC-SK2?
The PC-SK2 has a ¼" connection with both an internal and an external thread. This allows the pressure switch to be connected directly to various installation components without additional fittings or adapters. The connection should be watertight to prevent device failure.
How do I set the operating pressure on the PC-SK2?
The thresholds are adjusted using two screws. Screw A sets the switch-on pressure, while screw B sets the switch-off pressure. Turning clockwise increases the pressure, while turning counterclockwise decreases it. The difference between the thresholds should not be less than 1 bar.
Which pumps is the PC-SK2 compatible with?
The pressure switch supports single-phase pumps drawing up to 12 A when supplied with 230 V. It works with surface and submersible pumps in pressurized water systems equipped with a tank.
Does the PC-SK2 require a pressure tank?
Yes. The PC-SK2 is designed to operate in pressurized water systems with a tank. The tank stores water under pressure and limits how often the pump switches on between the lower and upper thresholds.
Where can I buy the PC-SK2 pressure switch?
As the manufacturer, we do not sell directly. The IBO PC-SK2 pressure switch can be purchased from our trade partners, installation wholesalers, and authorized online distributors. You can find the full range of pressure switches and controllers in the controllers category.
What is the warranty for the PC-SK2 pressure switch?
IBO – 24-month (2-year) manufacturer's warranty.
