An AC switch is specific for welders, and is primarily used for an alternating current of 50 or 60 HZ, and is suitable for a variety of motors with a rated voltage under 440V.
To meet welder needs, the switch is designed with 6 poles on a 30° switching position. Cansen’s cam switches are easy to install and operate, and we also offer customization services if none of the installation sizes meet your needs.

Switches are small parts of machinery, but their quality and function should not be ignored. Cansen is a professional rotary switch supplier,founded back in 1981. Since then, we have been dedicated to the production of superior quality switches. To manufacture high-quality switches, we start by creating compatible switch fittings in which we design and produce each copper connecting sheet by ourselves. Knowing that safety is the most important factor in the design and operation of step cam switches, we inspect the switches multiple times during and after production, testing for things like mechanical endurance, proof tracking, fire resistance, and more. If you need help finding the right switch for your equipment, contact us for assistance.
