The switches with 2 poles are available up to 3 kW and with 4 poles up to 30 kW. It can be used during service or maintenance activities to prevent the activation of the motor.

This 3-step control switch regulates EC fans, damper actuators, AC fan speed controllers or frequency inverters. It needs 10 VDC supply voltage. The device has an OFF position to stop the motor completely. Thus, the output signal is divided into 4 steps: 0 VDC and 3 other output voltages. The output for position 3 always equals the supplied voltage i.e. 10 VDC. The output ranges for positions 1 and 2 can be adjusted via internal trimmers. There is also a version with 2 predetermined voltage steps: SMT-D-4P-EM
