The Tenma 76-060 is a rotary dial switch with a long history. It is a toggle switch, like a regular rotary switch, but has two different positions, one for OFF and the other for ON. The switch was designed for two-way control purposes, such as lights, machines, or audio equipment. The switch is made from plastic and metal, and is available in a variety of colors and angles. Its advantages include the fact that it won’t wear down over time like a regular rotary switch, has good contact life and durability, and offers good control over the connected devices. It is fairly easy to install and use, and is available in various sizes and voltages.
