Rotary Switches

Rotary switches contain a series of contact points that are arranged around a rotor in a concentric circle. When the switch is moved, the rotor is rotated so that the contact points make and break contact with other points around the circumference of the switch. This type of switch is widely used in a wide variety of applications where multiple electrical circuits need to be activated, such as in industrial robots, heating systems and security systems.

A12503RNZBK Application Field and Working Principle

The A12503RNZBK rotary switch is a cost-effective electro-mechanical device and is widely used in the commercial and industrial market. This switch features 3 poles, 15 positions and boasts good electrical, mechanical and environmental characteristics. Being of a compact size, the A12503RNZBK is typically mounted on printed circuit boards and is suitable for many applications such as alarm systems and industrial machinery.

The A12503RNZBK rotary switch is operated by the user rotating the switch and establishing contact between the contact points. The contact points are arranged around a rotor, which is positioned in a concentric circle. As the switch is rotated, the rotor is moved and causes the contact points to make and break contact with other points around the circumference of the switch. When the correct contact is made, the required electrical circuit is activated.

The number of positions that the rotor can make and break contact with is determined by the number of contact points on the switch. In the case of the A12503RNZBK, there are 3 poles, each with 5 contact points. This equates to 15 switch positions in total.

The size and shape of the A12503RNZBK rotary switch make it suitable for mounting on printed circuit boards with through-hole technology. This is the same manufacturing technique used for surface mount devices (SMDs). The terminals are soldered directly onto the circuit board, increasing the robustness of the device.

The A12503RNZBK rotary switch has a number of benefits. These include a low cost, good electrical and mechanical performance, a wide range of positions and a compact size.

In summary, the A12503RNZBK rotary switch is a cost-effective and reliable device designed for industrial and commercial applications. It is a multi-pole switch which offers excellent electrical and mechanical performance, a wide range of positions and a compact size. The switch is operated by rotating a rotor, which is positioned in a concentric circle. As the rotor is rotated, the contact points are lined up and make contact with other points around the circumference of the switch, thus activating the required electrical circuit.
