BASO L61LL-1 Pilot Switch

The BASO L61LL-1 Pilot Switch is a heavy-duty auto-reset SPDT safety switch designed for standing pilot burner systems. As a veteran technician knows, maintaining the integrity of the safety circuit is non-negotiable; this switch serves as the critical link that identifies pilot flame failure and immediately de-energizes the main gas valve. This gas pilot safety control is cross-compatible with several legacy parts, functioning as a direct universal replacement for BASO 860-1, 861-1, 960-1, 961-1, and L61LL-3 models. Often identified by the field-equivalent HH71CC150, the L61LL-1 features a single pole double throw configuration with a normally closed (NC) contact rated at 125 VA pilot duty. The normally open (NO) side supports 8 Amps at 120 VAC or 1/4 HP, providing the rugged electrical overhead required for commercial cooking equipment, boilers, and industrial water heaters. Built to operate in ambient environments ranging from -40°F to 150°F, it ensures reliable standing pilot burner protection in demanding mechanical rooms.

• Universal Compatibility: Simplifies truck stock by replacing multiple BASO models and the HH71CC150.
• Automatic Reset: Eliminates manual intervention after brief interruptions, ensuring the system resumes operation as soon as the pilot is re-established.
• SPDT Versatility: Provides flexible wiring options for both safety shutoff and auxiliary signaling or alarm circuits.
• Rugged Electrical Ratings: Rated for 125 VA pilot duty and up to 1/2 HP at 240 VAC to handle high-demand gas appliances.
• Certified Reliability: UL Listed and CSA Certified to meet strict safety codes for commercial and residential installations.

Can the L61LL-1 replace the L61LL-1C or L61LL-3?
Yes, the L61LL-1 is technically identical to the L61LL-1C and L61LL-3 variants, making it a direct drop-in replacement without needing bracket modifications.

Does this switch require a manual reset button?
No, this model is an auto-reset switch. It will automatically close the circuit once the thermocouple or thermopile generates sufficient millivoltage, which is ideal for systems that do not require a lockout manual reset.

Is this compatible with electronic ignition systems?
No, this part is specifically engineered for standing pilot systems where a continuous pilot flame is monitored by a sensing element to control the safety switch.
