LV control and signalling is the everyday hardware of every control panel: contactors, overload relays, manual motor starters (MPCBs), plug-in and interface relays, timers, monitoring relays, pushbuttons, selector switches and pilot lights, and beacons, signal towers and sounders.
LED Controls Ltd holds deep stock from ABB, Lovato Electric, Finder, Emas, Carlo Gavazzi, IMO, Chint and Pizzato. Filter by brand and rating, and use the range list above to jump straight to the component type you need.
LV control and signalling is the everyday hardware of every control panel: contactors, overload relays, manual motor starters (MPCBs), plug-in and interface relays, timers, monitoring relays, pushbuttons, selector switches and pilot lights, and beacons, signal towers and sounders.
Pushbuttons and pilot lights are the operator's interface to a machine: illuminated and non-illuminated pushbuttons, emergency stops, selector and key switches, joysticks, cam switches, indicator lights and complete control stations. LED Controls Ltd stocks Pizzato, Lovato Electric Platinum and LPX, Emas, ABB, IMO and Chint 22 mm ranges plus Pfannenberg indicators.
Signal towers, beacons and sounders show machine status at a glance and alert operators to faults. We stock Pfannenberg and Emas LED beacons and sounders, Lovato Electric LTN modular signal…

Shop Relays →Rotary cam switches for on-off, changeover, motor-reversing, step and selector duties, in front-panel, door and enclosed versions from Emas, Lovato, IMO and ABB.
Shop Rotary Cam Switches →Time relays add on-delay, off-delay, interval, flasher and star-delta timing to a control circuit without a PLC. We stock Finder multifunction and modular timers, Carlo Gavazzi and Emas timers, Lovato…
Shop Time Relays →Every control panel is built from the same building blocks: switching devices to control loads, relays to handle logic and protection, and pushbuttons and indicators for the operator. Choosing the right rating and type for each keeps the panel reliable and compliant.
Contactors switch motors, heaters and lighting under PLC or pushbutton control. Rated by AC-3 motor current or AC-1 resistive current with the right coil voltage.
Plug-in, interface and solid-state relays isolate PLC outputs, multiply contacts and switch small loads reliably millions of times.
22 mm pushbuttons, selectors, emergency stops and pilot lights are how the operator controls and reads the machine.
