MR(36˃Step) Miniature Rotary Switches ˙Features 1. Diallyl phthalate resin ( UL94V-O ) which has excellent resistance to arc and heat, and superb insulation quality is employed. 2. The terminals are molded in to ensure the permanent seal structure that completely prevents flux entry through the terminals. 3. Adoption of the wiping mechanism for the contacting area to ensure contacting stability and reliability. 4. The variable stopper is provided to allow free selection of the desired number of positions (excluding MR4-2 type).

Circuit diagram ˔The circuit diagrams show the switches as viewed from the terminal side with the shaft fully turned in the counter-clockwise direction. 1. The required number of positions can be obtained by fully turning the shaft in the counter-clockwise direction and inserting the stopper hook into the select hole of the desired contact number. 2. Do not use the variable stopper when all contacts are used. [Example] Select Hole No. 5 to set 5 positions with MR1-10-Z. Select Hole No. 3 to set 3 positions with MR2-5-Z.
