Schneider push buttons: such as XB2 pushbutton, XAL-B pushbutton control box, XAL-D pushbutton switches.
In electronics, the switch is an electrical component which can break electrical circuit, interrupting current or diverting it from one conductor to another.The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts. Each set of contacts can be in one of two states: either 'closed' meaning the contacts are touching and electricity can flow between them, or 'open', meaning the contacts are separated and nonconducting.
