Replacement reed contact for paddle flow switches

Replaces the reed contact unit of the paddle flow switches in this range. It fits the inline versions from G 1/4" to G 1 1/2" and the insertion version. The contact unit sits outside the medium, so a worn contact is replaced without buying a new switch. Its position on the switch sets normally open or normally closed operation. It switches max. 40 VA, about 0.17 A at 230 V AC: enough for a PLC (programmable logic controller) input or a small relay, while pumps need an intermediate relay. Supplied with a 1.5 m two-core cable.
