Marine Signal Lamp Changer

Meets or exceeds the requirements of U.S. Coast Guard Specification numbers 195 (2086A) and 478 (2086B) including vibration test at 5-G’s, shock test at 40 G’s, salt spray and immersion.

• Gold Plated Contacts
• Terminal Connectors – Brass with Tin Electroplate
• Terminal Screws – Stainless
• Die Cast Alumimum Frame with Polyester Powder Coat Finish
• Turret – Injection Molded High Strength Plastic

We developed the 2086BLR Lampchanger under contract with the U.S. Coast Guard to meet Specification G-SEC-478 which includes a requirement that the resistance through the lamp circuit not exceed 0.010 Ohms, after extensive heat testing when running a 110 Watt halogen marine signal lamp. The “LR” in “BLR” stands for low resistance.

In order to achieve this low resistance, significant material and assembly changes were made to the 2086BLR lampchanger from the 2086B version, which include the following:

1. Elimination of one of the two Spring Contacts (between circuit board and turret) and replaced it with 16 gauge tinned copper stranded wire. This cable is threaded through the turret. A high temperature engineered plastic is used as a pivot with stainless steel tube to hold the turret instead of the solid stainless steel pivot used on our other lampchangers.
2. The other Spring Contact is doubled up to increase contact pressure. A higher conductivity spring material is used.
3. All gold plated brass parts have been replaced with gold plated copper.
4. The three colored terminals have copper inserts instead of brass.
5. Six contact plates on top of the lamp turret positions have an inlaid silver/nickel contact strip running the full length of the part through the tab overhang. This is the best moving contact material available.
6. There are six terminal resistors instead of only one and they are connected by 20 gauge solid copper tinned wire to create a parallel electrical power path to the back-up ring.
7. A heat baffle is mounted at top of the lampchanger to shield the top turret ratchet tooth from lamp heat. All other specifications are similar to the 2086B version of our lampchanger.
