Discrete Component Cube Type Sub-Base

·  DISCRETE COMPONENT MODELS.  All models contain replaceable components on circuit board.
200Meets NEMA, CALTRANS TYPE 170, FHWA TYPE 170, most states.
Our most popular model Load Switch!
Bare aluminum finish.
200-15Model 200 with 15 amp. rating to 165°F. Exceeds requirements
200-OICLMeets NEMA, FHWA TYPE 170, and most states. Model 200-15 with extra LED indicators on output circuits. Unlike competitor's models, LED failures will not cause load switch failure, signal lamp outages, or conflict monitor initiated flash operation. Exceeds requirements
200-OIBIModel 200-OICL with Bi-color LED indicators on output circuits. Bi-color LEDs provide diagnostics: Orange light: Full wave (ok); Red or Green light: half wave output.
A Superior discrete model Load Switch!


·  CUBE TYPE MODELS.  All models contain replaceable modules.
MOD 3 Meets NEMA, FHWA TYPE 170, most states. Modules have epoxy fill. Available with no epoxy (repairable). Bare aluminum finish
300 Meets NEMA, FHWA TYPE 170, most states. Unlike competitor's models, LED failures will not cause load switch failure, signal lamp outages, or conflict monitor initiated flash operation. Epoxy filled sealed modules are standard.
300-15 Model 300 with 15 amp. rating to 165°F. Exceeds requirements. A high performance standard cube type model load switch!
300-OICL Model 300-15 with extra LED indicators on output circuits. Unlike competitor's models, LED failures will not cause load switch failure, signal lamp outages, or conflict monitor initiated flash operation. Exceeds requirements
300-OIBI Model 300-OICL with Bi-color LED indicators on output circuits. Bi-color LEDs provide diagnostics: Orange light: Full wave (ok); Red or Green light: half wave output.
The best standard cube type model load switch available!


·  SUB-BASE.   A receptacle connector for above load switches.
LSSB Sub-base (socket) for 12 pin, blade type load switches, with panel mounting bracket.
