Copal MR2-3-Z Miniature rotary switch Datasheet

MR(36°Step)
Miniature Rotary Switches
RoHS Compliant
■ Specications
■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).

■How to Use Variable Stopper
[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.
Select Hole No. 2 to set 2 positions with MR3-3-Z.
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.
