[QUOTE="Rossy, post: 560064, member: 38336"] Hello, We have an old Alvan Blanch mill mixer machine used for processing and mixing grain for sheep and cattle feed. It is run by a single phase D215 Brook Motors motor that is plated as 5.0 horsepower (Hp) with a full load amps of 22.0. The motor has, for many years, been started with a manual 'start', 'run', 'off' switch also made by Brook Motors. The starter model is HC1 and is plated as being single phase, 36 amps and 50 hertz (Hz). There is now a fault with the switch gear. The process was to move the switch to 'start' and then, when the motor was up to speed (usually, say two or three seconds) move the switch to the 'run' position. However, the switch no longer stays in the 'run' position. I understand (but may be wrong) that the switch would stay (be held) in the 'run' position by a magnetic switch. When the magnetic switch was turned off, the switch would drop and the machine would stop running (be in the 'stop' position). It appears that there is a fault with the magnetic switch and would like to explore the options of repairing the existing switch or replacing it with a modern alternative. I have photographs and diagrams of the switch and the motor connections and will try and upload these. Both switch and motor were working fine about two weeks ago. Thank you in advance for your assistance. [/QUOTE]
