Description :

Application of stepped speed:
1. Once applicable speed is decided, as speed is changed, variable electric resistance value can be fixed.
2. Parallel type: the switch first makes contact with the connecting terminal, then returns to the original terminal point.
3. Serial type: the switch leaves the previous connecting point, then makes contact with another terminal point.
4. Either type is applicable, please wire accordingly. When using the parallel type switch, an open-circuit mode is created at the instant of switching, where a rapid increase of motor speed must be taken into precaution.

Specification :

1. Model: SS21, SS22, SS31-HR, SS32-HR.
2. Power range: 50/60Hx.
3. Max. current allowed: 2A, 2A, 3A, 3A.
4. Please refer to the attachment.
