Replacement pressure switch for WP series water pressure pumps.
Please note that different pressure switches are used for the first and second generation WP_08 (2.1 bar) and WP_13 (3.1 bar) pumps, but there has only been one generation of WP_20 (4.2 bar) pumps.
The main difference between the pressure switches for the first generation and second generation WP_08 and WP_13 pumps is the positioning of the electrical connections: please refer to the images or contact us if you are unsure.
