SureSwitch is an electronically-controlled relay that can be used to replace single and two-pole contactors commonly used in air conditioners, heat pumps and other applications. A patented switching algorithm reduces arcing between contacts, which nearly eliminates pitting and welding for a longer life. The switching mechanism is sealed to prevent intrusion from insects and other debris.
