The Safety Bipolar S/L is a specialized bipolar safety switch that includes a signal light (S/L) to indicate the operational status. This device disconnects both live and neutral poles for complete electrical isolation, while the integrated light provides visual confirmation of power status. Ideal for boilers and burners, it enhances safety during servicing by clearly showing when the unit is powered off. The combination of protection and indication makes it a convenient choice for technicians. Replace your old safety switch with this model to improve both safety and usability.
