Immediate action switches “Tumbler” type are designed for commutation of electric circuits of direct and alternate current in radio-electronic equipment.
Tumblers are designed in all-climatic modification.
Tumblers are manual control devices.
Constructive modifications:
- PT3-10V – handle fixing in two end points and mid position;
- PT3-20V – handle fixing in one end and mid positions;
- PT3-30V – handle fixing only in mid position;
- PT3-40V – handle fixing in two end positions (without mid position).
