SHOWA FLOAT SWITCH OLV

The OLV type float switches enables an electric ON or OFF signal to be sent according to the fluid levels inside the tank. Using this function, it is possible to: turn off the unit or machinery; switch on indicator lamps or set off buzzers to inform of the pump's fluid level situation.

Possessing stoppers at both ends, the apparatus ca be utilized in deep or shallow fluid levels.

The float switches operate using low level voltage, so please ensure to attach a relay.
