This is a Circuit Filled icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,000 icons, all in the same style and quality.

We've received the idea on June 30, 2013 and created the icons on August 18, 2013
Hi there, You really need to extend the existing "Electronic Components and Circuit Symbols" icon set.... - Diode - Motor (Step-Motor) - Relay - Potentiometer - Sensor - Crystal oscillator. Regards
