It is an SPST normally open switch (1 Form A) that replaces electromechanical relays in AGENCY APPROVALS many applications. It is constructed using a GaAlAs LED for UL actuation control and MOSFETs for the switch output. I n cUL addition, it employs current-limiting circuitry to provide overvoltage protection.
