A close-up of 3 "Frankenstein" power line break switches not in service. They are at the Oregon Electric Railway Museum substation in Brooks, OR. They will soon be mounted up on crossarms above the transformer they are resting on as part of the museum's 22,000 volt replica power line and substation. The small multipart switch insulators are made by Locke and are dated 1937. The switches were made by Pacific Electric Mfg. Co. of San Francisco. They operate by a vertical pull rod with a handle on the pole, which operates a horizontal rod and tilts the middle insulators up and back, breaking the connection. The Y shaped rods sticking upward are arcing horns and quench the large sparks made when the switch set opens under a power load.
