HEMAADRI control switches are cam operated modular switches. They are perfect for industrial applications such as TRIP and CLOSE operations of circuit breakers. These switches are manually operated and robust in design. Designed to accommodate two isolated “Double Break” silver alloy (contact rivets) contacts per stage at 180 degrees disposition. Modular design of the switch allows many contacts depending on customer requirements. The operating knob is attached to a steel shaft that rotates the cams in each contact stage, thus switches contacts. HEMAADRI control switches are RoHS compliant.

Patented “Touch Proof” design in the switch enables configuration of finger protection as an option. This means the finger protection can be added to or removed from the switch depending on customer requirement. Even with finger protection, any type of lugs can be used for connecting wires to the switch, which makes it special.

The cam switches from Hemaadri can be programmed to customized contact configurations per customer requirement in addition to stay put or spring return operating mechanisms.
