DW26 series rotary switches

Classification

1 Classified by utilization:

1) Change-over switch;
2) Motor switch;
3) Control switch

2 Classified by operation

1) Limited movement;
2) Spring-return;
3) Limited movement with spring-return.

3 Classified by contact system

1) Switches with limited movement could have 12 layers in maximum (for 32A and below), and for 63A and above could have 8 layers in maximum;
2) Switches with spring-return could have 3 layers in maximum;
3) Motor switches could have 6 layers in maximum.
