JS ST-70AB Basic float switch

Description

The JS ST-70AB Basic Float Switch is a primary float switch to control a pump for tank filling or tank emptying. ST-70AB is used for wall or tank mounting. It contains twin liquid-filled balls that work on displacement.

Levels can be achieved by positioning the two weights to give a differential of 50mm to 1000mm. 110v 10 amp maximum or 230v 7.5 amp maximum inductive loads can be used for pump control. A contactor/starter/control panel must be used if the pump inductive load is higher. The same applies to applications for three-phase pumps.
