Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions

Circuit tracers or signal tracers are used to troubleshoot circuits. They are relatively simple electrical testing instruments that enable electricians and other users to locate, trace and identify common electrical problems such as breakers, shorts

Switch boots protect switches from contaminants such as dirt, dust, gas, and liquids.  They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker and rotary switches.

Printed circuit board (PCB) fabrication services design and fabricate circuit boards. They differ from electronic manufacturing services, which populate and assemble boards. 

Flexible circuits use polyimide films and other foldable substrates to meet the requirements of complex electronic manufacturing applications

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.

Printed circuit materials have copper-clad surfaces for the fabrication of electronic and electrical circuitry on printed circuit boards (PCBs), printed wiring boards (PWB) or flexible circuits

Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers

Closed circuit TV (CCTV) is used for area surveillance and remote monitoring. Some systems can record events and trigger alarms

Thin film circuits and products are metallized or plated onto ceramic substrates

Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits

Circuit protection devices are used to protect electronic components from unwanted transients such as current and voltage surges, electrostatic discharge (ESD), lightning, spikes and other signals that can imperil the operation or damage the component

Ground Fault Circuit Interrupter (GFCI) testers check for the integrity of GFCI devices

Electrical contact and electrode materials are soft, high conductivity, oxidation resistant materials used in circuit breakers, relays, and for EDM applications

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.  They often have a second phase in order to provide anti-welding and/or arc resistance
