Product Description

Product Description

Durable 16A/250V T150 Position Rotary Switch for High-temperature Working Conditions

It is a multi-position, multi-circuit mechanical switch that switches the on/off state and combinations of circuits by rotating a knob, thereby achieving power adjustment or function switching of equipment. This switch features a high-temperature resistant insulated shell and gold-plated contacts, specifically designed for high-temperature operating environments such as ovens and heaters.

Working Principle:
I. Rotating the metal knob on top will synchronously rotate the central black moving contact bracket.

II. During rotation, the moving contact will make or separate from the stationary contacts at different positions.

In this way, multiple circuit combinations can be achieved, thereby controlling different operating modes or power levels of the equipment.

Gear Selection:

The gear selection of a gear switch is essentially achieved by rotating the knob to allow the internal moving contact to contact the stationary contact at different positions, thereby switching the on/off combination of the circuit and realizing the adjustment of the power or function of the equipment.

Gear position	Function description	Contact on/off logic
0 (Off)	Power off, no load.	All moving contacts separate from stationary contacts, circuit completely disconnected.
1 (Low/Single Circuit)	Low power operation, only one load group operates.	The first group of moving contacts contacts the corresponding stationary contact, only one circuit is conducting.
2 (Medium/Dual Circuit)	Medium power operation, two load groups operate.	The first and second groups of moving contacts contact the corresponding stationary contacts, two circuits are conducting.
3 (High/Triple Circuit)	High power operation, three load groups operate.	The first, second, and third groups of moving contacts contact the corresponding stationary contacts, three circuits are conducting.
