We recommend to let this water level switch interrupt your SSR control signal when the water level is too low. This will prevent your element from heating when there is too little water in the kettle, which could damage the element.
The float switches can be mounted upwards or downwards. If you flip the float ball upside down, the switch is changed from normally open to normally closed.
Temperature Rating -30 - +125C Material SUS304 Cable length 30cm
Warning: you should use this switch to interrupt the low voltage, low current control signal for the SSR, NOT the high voltage, high current power to your element!
