When you need to make very tiny measurements, even noise in closed relays can throw you off. [Marco] was able to observe this effect and wanted to build a switch that didn’t have this problem. He ...

There are certain challenges we all will have to face sooner or later. Changing a flat tire in the rain, trying to put on a shirt that doesn’t quite fit, or producing a 16 position rotary switch for a ...

Transfer time is about 10 msec. The switches feature continuous ratings from 20 to 200 A at 600 V. Some configurations allow for four positions and 12 poles. To prevent contamination, switching takes ...

Schweitzer Engineering Laboratories, Inc. has released its new rotary switch product family. In 2010, SEL purchased VoltAmp, a manufacturer of rotary switches. Building on VoltAmp’s 40 years of switch ...

Elma Electronic recently revealed the multi-function MR50 0.5-inch rotary switch for harsh environments. Suited for space-constrained handheld and mobile devices, the rotary switch offers precision ...

We show here how an imidazolyl ring incorporated into a rotary switch based on a hydrazone enables a switching cascade that involves proton relay between two different switches. The switching process ...

Vying for position as a contactless alternative to mechanical rotary switches, the AS5030 and AS5130 8-bit absolute magnetic rotary encoders integrate push button and low-power mode features. Both ...

Touting variable speed operation, a new series of rotary ac switch has three major functions. It serves as a main power switch; as the switch is rotated into the on position, it enters the ...

Toggle switches are triggered by a device in one of two or more positions. Household light switch wiring is an example of a toggle switch. The toggle switch is usually a two position switch. The ...
