CAM Operated Rotary Switchesare used to perform make and break operation in a sequential way by rotating the switch to different positions.
The CAM, which closes and opens the contacts, has rotary movement in multiple positions, thereby controlling multiple circuit functions.
Further the flexibility in the switch type selection covering various current / voltage ratings and options to select the number of contacts, is an added advantage. This ensures that a right switch is chosen for the desired application. CAM Switches thus offer complete design flexibility to assemble complex switching programs, contact ratings and customize all switching applications. Cam Switches are suitable for AC as well as DC switching applications.
The basic operating mechanism of cam switch is intended to suit application coupled with Quick-Make, Quick-Make-Quick-Break and Spring Return operating mechanisms.
The CAM switches offers versatile mounting options in addition to standard panel / flush mounting and other special features like single hole, door interlocking, padlock, lock and key for various needs. The wide option such as type of knob, front plate colour and customized marking on the marking plate eliminates the need of separate label on the panel.
Superior quality of engineering material and double butt contacts with silver bimetal on copper / brass provide stable electrical performance. The high-grade engineering plastics with high tracking index like nylon, silicon and glass filled polyamide for the components ensures greater mechanical strength.
Advanced manufacturing processes for CAM switch components under stringent quality conditions ensure durability, reliability and enhanced life.
