Rotary switches are on-off switches that permit the electrical connection to be made in various combinations of available stages. 71BS30-01-3-04N is a typical 3 stages,4 shunt poles,30 degree angle of rotation rotary switch. With its superior performance, this rotary switch is ideal for use in different areas where multiple electrical connections are required.

Application Field:

71BS30-01-3-04N rotary switch is specifically designed for applications which require multiple electrical and mechanical choices,such as generator selector switches, position selectors, multiple motor starters, and many other multi-circuit applications. Moreover, its structure of two concentric rings makes it suitable for controlling circuits of small current,dc circuits and electro-optics.

Working Principle:

This rotary switch consists of a rotating plate complete with external connections. The plate is provided with two concentric grooves in which are inserted bolted contacts with silver contacts. The contacts are fitted into holders formed from sheet steel which have been cold headed to form a shoulder at the contact level.

When the switch is in its \'off\' position, innner and outer ears of the contacts are both closed, thus disconnecting the electrical circuits from each other.When turn the switch in clockwise direction, the barriers between the poles will close gradually as the ear moves, and the inner and outer ears of a given pole will come into contact with each other. This connection can be made infinitely adjustable between 0 and 30 degrees.

Conclusion:

In conclusion, 71BS30-01-3-04N is an excellent rotary switch with superior performance and wide applications. Its working principle is quite simple and practical, making it an ideal choice for different application fields.
